Normally I keep my Start Bar at the top of my screen. Some applications don't realize this and open underneath it. It means I have to move the start bar out of the way to get at the window controls for that app. Normally, I just move it to the side and move it back when I'm done.

However, in Windows 7, a blue bar is left in the start bar's place afterward.

It blurs the objects underneath, but passes down mouse events so click and move events still work.

Anyone know what this is or how to get rid of it?

EDIT: It appears that when I move the start bar back to bottom of the screen and back to the top the "glitch" is removed.

(Windows 7 RC Build 7100)

I think you got that build number wrong... it's 7100 not 1700 – RCIX Jul 20 '09 at 4:47
Thanks. Dyslexia or super fast fingers: you decide ;-) – y0mbo Aug 3 '09 at 15:16
Just a tip. Instead of moving the taskbar when it covers a window..Hold down the windows button and push the arrow keys. That should resize the current window to where you can access the top controls. – prestomation Aug 3 '09 at 17:01

Having played around a bit on my own Win7 machine, it looks like it's a "ghost" of the task bar - probably a bug. I got rid of it by moving the task bar around the screen until the "ghost" disappeared and the bar was where I wanted it. I think the most reliable move was from bottom to top.

This was mentioned in the release notes ( of the Win 7 RC as a known bug which will be fixed until RTM. – Joey Jul 19 '09 at 20:12

Seems like a known bug. The discussion indicates it may be video driver related, but can't find anything official on that.
