This little glitch happens when i wan’t to switch from skinless interface into skinned one.
If you start Simple interface in Skinless mode,open Settings and check “Enable skins for Simple user interface” and click ok. After this is done,you’ll get the glitch in the attached image…
I can’t upload pictures >:( (http://forum.avast.com/index.php?board=1;action=display;threadid=8085) but mine skinless is giving other strange answers in that two lines: Yes and Yes :
It also happens when you have enabled “Enable skins for simple user interface” and than disable it. I get no and no
Thanks, this is now fixed.
Ok, fixed here too.
No problems switching from skin to skinless and viceversa 
Working just fine now.
