Now, correct me if I'm wrong, but it seems to me that the problem lies with the event handler that we use for the main display. We've had similar problems with the scrollbar for a long, long time. I've read in the pasat that this occurs because the event handler that the main LyX window uses is 'incorrect" in some xforms sense. I know not what I'm talking about really;just regurgitating old memories. If this is so, then the fix is to handle the main window's events in an xforms-correct way. Angus
