I don’t quite understand. How do you start the screen-saver manually?

I’ve just checked that the following works under XP with build319:

  • Control Panel, Display settings
  • Screensaver tab, select avast antivirus, click Properties.
  • Select a real screensaver (I use Starfield for experimenting) and confirm with OK

Now:

  • Click Preview → it works
  • Wait for the screen saver to start after X minutes of idle time → it works.

So?
