I bet this is due to panframes. Add to your instructions: OpaqueMoveSize 200 EdgeThickness 0 Move Does it disappear then? (The use of OpaqueMoveSize is completely unnecessary here, FWIW.) In which case, the problem is most likely the events the pan window receives as the window is moved across it (and hence the pointer is then inside of the panwindow also.) I don't believe your patch to be a good enough fix though for this -- it seems to be orthogonal to the problem; at least in terms of how I am able to reproduce it and potentially "fix" the issue. -- Thomas Adam
