While looking at Xdnd I discoverd that jx (or at least their demo program) 

cannot paste from fltk programs.  This appears to be because JX barfs if
the pasting program does not respond correctly to the TARGETS XConvertSelection.
I added a response that fltk only can do text and this seems to make it
work.
