   Somebody recently posted some source in comp.windows.x which was for
creating widgets on multiple displays from one program. I tried it on
a Sun, and a Sony and it worked, but on my HP (HP9000/400t, HP_UX 7.03,
server = X11R4, libraries = X11R4) it hangs up on a second call to
XtRealize widget. Anybody got any ideas as to how to make it work on my
HP?
