I am using two screens -- a Dell monitor is virtually above the laptop screen. Several times the computer has frozen up while I'm running ediff within emacs. The computer gets into a state where I can't change the input focus. Only one window has the focus. If that window is an xterm or emacs then I can try killing emacs manually, but even then there remains a blank window where emacs was, and I still can't change the focus. Menus don't respond either. The only solution is to reboot. The bug seems to be reproducible as follows. I have the emacs window in the lower, desktop screen, but with the top of the emacs window close to the top of the screen. I start ediff, usually with ediff-buffers. The little ediff window appears at the bottom of the upper screen, since it can't fit above the emacs window in the lower screen. From that point on, the window focus is broken. It seems that having the main emacs in the lower screen and the ediff window in the upper screen is what causes the behavior described above. If I keep the emacs window away from the top of the lower screen, so that there is room for the little ediff window to fit in the lower screen, then the problem does not occur. Maybe emacs has nothing to do with this bug -- maybe it is only exposing a bug in the window manager. Any suggestions?

More information was requested five years ago, but no further progress has been made, so I'm closing this bug report.
