Comment 4 for bug 139361

Hmm, this is probably caused by a few things fighting each other. Also, the 'hotspot' awn uses to figure out that your mouse is at the edge of the screen may not be above the other windows.

There's a rewrite going on which hopes to simplify everything, and sort out the little niggles like this. Thus I'm marking this to be fixed for 0.2.6. Thanks for the report.
