- My main app widget implements Tek-style crosshairs with event handlers

- If I drag the pointer into a popup window, ButtonMotion events continue
- to be reported to the main app widget even though no grab is in effect.
- Why?
-
- ButtonPress causes an implicit grab to be in effect. The grab is
- (faulty memory here) in GrabModeAsync. You will still get the
- enter and leave events and you might be able to transfer the grab
- using those.
