I have a couple of questions about the events generated by the
OpenWindows2.0 server:

0) Background:
	Using a Sun4/330 GX with an openwindows2.0 server and uwm
(for old times sake). My event mask is:

      xswa.event_mask = ExposureMask | StructureNotifyMask
                   | ButtonPressMask | ButtonReleaseMask | ButtonMotionMask
                   | KeyPressMask | PointerMotionHintMask;
      xswa.do_not_propagate_mask = VisibilityChangeMask;

1) I seem to be getting EnterNotify events every time I move the mouse
   (with all buttons up), even when I don't think I am entering any
   subwindows. Why ?

2) I seem to be executing the code for the MotionNotify event even though
   no buttons are pressed. The behaviour I want is to select and move a
   window when the a mouse button is pressed.  What I get with OpenWindows2.0
   is subwindow movement all the time !

The code works fine under an X11R4 server, I do not get any of the extra
EnterNotify events.  Anyone else run into this problem ?  I will post more
code of the event loop if necessary. Thanks, Paul.
