I use motion events to implement a drag-selection of text.  Using the
XSun server from the X11 distribution, I only get motion events when
the mouse buttons are held down.  I figured that epoch was filtering
out the motion hints when the buttons are up, or that the server was
only asked to relay them when the buttons are down.

However, I recently tried to run epoch under the Sun4.1.1 Openwindows
server, which supports OpenLook.  I wasn't using the olwm window
manager, just the openwindows server.  I got motion events all the
time, and my routines all broke.

Which server is correct (according to X docs), the X11 distribution or
Sun openwindows?  I can imagine cases where I would want the motion
hints when the buttons are up, so I don't think epoch should make this
choice.  Is the X11 XSun server broken?
