hi

X automatically does pointer grab when the mouse drags (i.e. press and hold
the mouse button while moving it).
It is possible to override the auto grab settings (i.e owner_events, etc)
with a passive grab (e.g. XGrabButton)

what if:

1. the user presses mouse button 1 (and holds it down)
2. the use moves the mouse
3. the application calles XUngrabPointer -> will it ungrab ?
or..
3. the application calles XGrabPointer  (withough XUngrabPointer first) ->
will it regrab ?

thanks,
erez.
