Sometimes the window goes "white" to be more specific than blank and
sometimes it just freezes up and doesn't respond to clicks on it. If I
hit the X gnome asks me if I want to "Force Quit" immediately. I also
notice the tray icon disappear on occasion. It is rather difficult to
duplicate. I'll often go days without the problem, then it will show
up. Sometimes it will happen a few times in a day. It doesn't appear
to be related to frequency of use. Sometimes it happens when Banshee
is paused and not doing anything.
