Hi Greg,

first of all thanks for your quick reply :-)

I assume you refer to this comment:

; Be sure the mouse cursor is invisible and at the default location. We
; need to do that here, because our mouse interrupt handler doesn't set the
; mouse position if it hasn't changed.

I surely read that before but somehow got the notion that it was something
special about the way the interrupt handler works on that machine/device.

But now that you pointed me there I understand that it is a more general
information suitable for most scenarios.

Thanks again for the hints, which should make me go into the right direction :-)
