I was going to post about this when I searched and found your post. Yes I have the same problem, even on the latest release, though it does fix some other problems. I've found that if I put my mouse over somethnig on AIM that brings up a large tooltip text or something of the sort, that's the time this will happen. What I was also going to say is that this could be quite useful if harnessed properly. It would be nice to be able to move the intire contents of your computer one desktop over. Also it would be nice to be able to move one screen's contents to a different screen.
