Fix mouse pointer handling on multiple screens

Browse Source 
The fix in 786b589d95 for the
"Cannot click buttons more than once without moving the mouse cursor"
did not correctly handle setups with multiple screens in one display.

We need to handle the case where the first XQueryPointer returns
a different root window than the default one.

This fixes bug 597386 (agaion)
