Subject: Problems with mouse cursor in GRX

I have just started experimenting with Csaba Biegl's LibGRX, which 
looks great so far, but I have noticed a strange problem with them 
mouse cursor.

Whenever I move it up to the top or far left side of the screen, and 
then drag it towards the top-left corner, it gets stuck and "jumps" 
erratically. (This is in 800x600x256, with VESA driver. In 320x200 
there is no problem....) I am using the event queue mode to handle 
the mouse, with a statement something like :

GetMouseEvent (M_BUTTON_DOWN); ( Can't remember the exact function 
                               name)..

Any ideas why this is happening. Also, how does poll the mouse in a 
loop in your program (ie. not using the event queue). Does one say 
something like GetMouseEvent (M_POLL) ?

Thanks for any help!
Mark.
