I'm writing a program based on Xlib and during testing under
the Openwin environment and X11R4 I have noticed a difference
in the event handling.

An event mask of: ButtonMotionMask|PointerMotionHintMask in
a program compiled and linked width Openwindows2 and X11R4 results
in a different set of events sent from the server.

X11R4 gives the behavior described in O'Reily's Xlib programming
manual in that motion events is sent by the server only when
a pointer button is pressed.

With Openwin the server sends motion events regardless
of the state of the buttons.

What is supposed to be correct ?
