I have run into this on Windows systems. It must have something to do with
the fast event detection and handling under MS Windows as I ddo not have
this problem under UNIX with X windows.

My work around is inserting a wait statement which allows for my finger to
get off the mouse button.

cursor,x,y,2,/dev ;Read position
wait,0.5
