It's not unusual for X clients to create 1x1 pixel windows which only exist to receive events, but such windows are usually hidden by making them InputOnly. You could possibly explore this a bit using xwininfo, to determine if this is a bug with VirtualBox (where the window isn't being correctly marked as hidden) or XWin (where the window is being show, desipte the fact it should be hidden) -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
