Surely you can come up with something more informative than that! :-)

Whose server?  OpenWindows?  MIT?  Other?

Probably not, but most likely you have some mistake in your program,
rather than the fault lying in the server.

From what you say, it sounds as though you are asking for
ButtonPressMask|ButtonMotionMask on a window, and are getting
ButtonPress events but no MotionNotify events.  According to my reading
of the protocol document, this ought to work (ie, you should get both
ButtonPress events and (when appropriate) MotionNotify events), and in
a simple test program I just tried it does work.  (I'm using the MIT R4
server.)

If you are asking for ButtonPressMask|ButtonMotionMask but aren't
seeing MotionNotify events even when a button is down, something odd is
going wrong, and I would have to see the code to guess what's the
matter.  If this is not true, I'd need to know in what way it is
inaccurate....
