Yup, same track. On my computer it appears as a blink of the unhilight color.

I believe that the problem is with the application closing itself down and
unmapping itself. The proper fix would be to redo the unmapping so that
whenever a window is unmapped, it unmaps the frame first. I am not entirly
certain how to do this when the application kills itself (q in xv).
It might be possible to do this by modifying the windows event mask.

That is very difficult for me to do, I have a very fact computer. :)
