[Bug] Wrong-way scrolling

The resident protection manager has a service list.

Scrolling it page-down by cliking in the scroll bar scrolls content down to the right position by warp-around.

I’ve lost you there completely… it scrolls exactly as it should scroll. If you roll your mouse wheel down, providers scrolls down as they should… if you scroll your mouse wheel up, they scroll up. Nothing weird in that IMHO. Same thing with Page Up and Page Down or cursor (arrows) keys. I don’t see any wrap-around on my copy of avast!, everything scrolls to the end and start point in providers part of the panel.

Basic or enhanced interface ? Or, you meant, avast! On-Access-Scanner ?
???

Working perfectly here… No problems at all 8)

Basic interface, window that spawns with a normal systray click.

Exclusively by cliking in the scroll bar under the cursor (wich scrolls it a “page” at a time).
Scrolling up also warps-around (one cycle to many) to the right position.

avast is v4.6.623 home free, automatically updated.

But maybe it is just an OS bug (Windows XP SP2 Fr). :-[

And how do you judge that it “warps”?

I think what is happening is that you end up back at the starting point (page), therefore you consider it wrapping. In actuality, the mouse has “reset” itself to the start. It is a little quirt with mouse operation that can even happen on other pages or programs using the scroll bar.

It really is not a problem. Sometimes the mouse “lags” a second or so behind movement. Naturally, when we see that it does not move accordingly…What do we do?..move it some more. The mouse (system) retains the original path and ultimately we may find ourselves “wrapped” back at the preceeding page or the top/bottom limits of scroll.

Happens with any OS if conditions are right.

mmm… I see Avast! is the MOST flawed software of the world… ;D… Alwil Team, help us!!!.. need a complete demolition of the code!!!
(ironic, obvious)
Italian Proverb:<When you see too many lacks in your love, love is named “hate”>

Select an icon that stays visible whatever the scrolling position of the list: 'Web shied" and “Instant Messenging”.
Scroll the list as said, and instead of moving 2 spaces, the selected item scrolls past border and comes back through the other boder, to settle at the correct position.

It is just a graphical glitch on the scroll effect, end result is fine.

(I Just thought of testing this)
It happens only when “smooth scrolling” is activated in Windows, normal setting jumps without scrolling effect.
Most certainly an OS glitch in fact, don’t bother.

Techie101 :
-Goes to the correct position.
-A mouse has no start and doesn’t reset. Mouse pointer either.
-There is no lag, no drag operation, a single clic, no mouse move after.

Kamulko!
Last week I sent around 40 bug reports about a forum engine, so don’t you complain ! ;D

You must have a very slow graphics card… :wink: On my machine, it scrolls faster than I’m able to examine, I tried about 20 times and couldn’t recognize the icons while they were moving… :slight_smile:

Yes, people he is right… only when Smooth scrolling feature is enabled in Windows. Actually, it’s not the bug in OS, most likely it’s somewhere in avast! code, something that fights with Smooth scrolling feature in Windows. Similar problems we had before with mouse pointers and stuff like that, remember ? Maybe it’s something we haven’t noticed before…

Edit: Yes Vlk, it scrolls so fast it’s almost impossible to see what are those icons that passes by… but the problem is, it looks like it makes circles, like it runs wrap-around… but only one time…
When Smooth-Scroll List Boxes option is disabled, everything is OK, but as soon as you enable it, problem starts to show in avast! provider list…

Thanks for reply, Musaran.
I say only this: most of your observations aren’t “bugs”. I’m not an experienced user and I see - learning and tryng - how many strange things are only hidden parameters.
So, please, consider that is not a wasted time to read and search deep-inside the program.
Is true: you really can find some interface’s bug. I think this isn’t important. I think how Avast! is easier to use also for the customers who want a light graphical panel: SZCraftec’s work are perfect for this.
Cheers! :wink:

Thanks for your opinion Kamulko, but avast! On-Access Scanner GUI uses standard, actually your current Windows visual style. Skins that we (Martin, RejZor, Darren and myself) make only affects avast! On-demand scanner and few windows (explorer extension)…

Hi, SZCraftec,
I know you’ve reason… but Musaran’s point-of-view (as he said also in other parts of Forum) is that Avast! should be more user-friendly with some repairs at interface’s look. I think so: if an user appreciate only a self-configuring program, who work without inputs, don’t need to open the additional panels. Is different for other customers who put the hands in personal configuration options.

For Musaran: I use XP SP2, smooth scrolling enabled… and I have a low level graphic card: I don’t have any problems 'cause the icons you say are very fast in scrolling. Maybe TOO fast for human’s eyes ;D

This setting is available through:
-System properties (Windows+Pause Keys shorctut)
-Advanced tab
-(Performance) Parameters button.
-Visual effects tab.

I think I have seen this glitch in other programs too, but I am not sure.

Same for me.
Select one and concentrate on the hilight.
Anyway it is easy to notice they do move way to much for a 2 space jump, and do move the wrong way for down scrolling, it ruins the intended smooth scroll effect.

Note that fiting all services in the window (as I suggested elsewhere) would “solve” the bug. ;D

I completely agree on this one. If it’s possible, to line up all those providers in the same Window, it would be great. Unfortunately, I don’t think it’s possible, just because the fact that some people still use 800x600 pixels resolution, and some are still on 640x480 pixels (believe it or not, I have visited many customers that still work on 14" monitors)…

Cheers !

No need to resize, there is room enough.

(My first computer was a macintosh at 12", 512x384. Some programs didn’t like it. :D)

But this is somehow off-topic.
