Thanks for the suggestion...I should have thought of that... ;)

The events appear only after the next event is generated. =20
Specifically:

1. I press the left mouse button and nothing happens.

2. I release the left mouse button and event 1 appears:

  ButtonPress event, serial 18, synthetic NO, window 0x1e00001,
      root 0x3b, subw 0x0, time 270147181, (74,175), root:(852,388),
      state 0x0, button 1, same_screen YES

3. I move the mouse one pixel and events 2 and 3 appear in
   reverse order:

  MotionNotify event, serial 18, synthetic NO, window 0x1e00001,
      root 0x3b, subw 0x0, time 270149407, (74,174), root:(852,387),
      state 0x100, is_hint 0, same_screen YES

  ButtonRelease event, serial 18, synthetic NO, window 0x1e00001,
      root 0x3b, subw 0x0, time 270149407, (74,174), root:(852,387),
      state 0x100, button 1, same_screen YES

I hope this helps.  Let me know what I can try next.

Eric
