Yes, I would like to know whether a program is started on the same X 
display.

And yes again, the program I would like to modify uses the gnome 1.x 
libraries
and was created with Glade 0.6.x. The program's main window is a GnomeApp,
and there are two properties (WM Class and WM Name) that I can set in Glade.
I guess these could be used to find out whether a window is registered 
(still running)
on the X display I try to run the second instance. The question is how?
