TaskBar Problems

Is there anyone who knows why the taskbar keeps flickering at the bottom of the screen when graphics is flipped or drawn on the screen. This happens randomly and I can't see any logic in it.
Please can someone help me to get rid of this problem..!

This only happens when the taskbar is set to "autohide" and to be on top of ather programs.
I'm useing windows XP.

I havb't had a problem likle this under 98 so maybe it's jsut with xp!

I did read that someone else (or maybe it was you?) had a similar problem in Blitz Plus (is that what you're using?), but I just tried AutoHide/Always on Top and didn't get this problem...
