when 7 RC boots up the start bar has an extension bit which looks like a blank section of the actual bar, just below it. I can get rid of it - by moving it to the bottom or right - but every time the computer starts up the random extension comes back, it is just a bit of a pain and wondering if there was something i was missing. btw I have the start bar at the top (because i like it that way), as thin as possible and the problem does not go away even when i lock the taskbar. the extension bit gets added to if I resize the bar but not removed when making it smaller. the rest of the RC appears to be working fine though Blue Screen of Deaths much more than the beta did (which was maybe once compared to the 4ish times that RC has done it to me) thaks

If you switch to a high contrast theme, I believe this problem will go away. It seems to only affect the Aero themes.

well thanks, but for 7 i want to be using the aero theme because it quite clearly looks soo much better anyone else got any ideas...?
