I have an app that accepts both stringFlavor and javaFileListFlavor objects
dropped onto it.  This is working well under Windows and Mac OS X.  I just
tried testing under Linux and my drop area isn't recognized there.  When I
drag either a string or file object the cursor icon show a circle with a
diagonal bar across it indicating "no".  

My code is patterned after the DragFileDemo code on Sun's site.  Actually I
just tried running the DragFileDemo program on Linux and it doesn't work
either when the drag source is outside of the app itself.  Perhaps D&D just
doesn't work well on Linux?

Anyone have any thoughts why this would be working on Windows and Mac but not
Linux?  Any way to get it working?
