I've run into this problem a few times and I have absolutely no idea how to fix it or how it is caused. For whatever reason, sometimes a window I have open becomes "always on top" and the only way I can fix it is by closing and re-opening the window or application. Very annoying.
Anyone else notice this and/or know how it is triggered/what keyboard shortcut I'm mistakenly pressing or something?
Seems to be a common issue on 7, I noticed it since the RC and unfortunately it's not fixed in the retail.
ANd it happens quite often too (w/o using the keyboard, so unlikely an accidentally triggered shortcut).
To me it looks like some sort of timing issue and Windows "forgets" that the window in question is still on top and garbles up stuff....
However for me it usually works to click into "ontop" window and back into the one I want to get to the front, didn't have to close and reopen so far.
