Thanks for the problem report.

I did some testing against Xserver 1.7.1 with xevent [1] and xdotool [2] to 
position the mouse pointer, but I wasn't able to reproduce the behaviour you 
are seeing.

I really have no idea how to get started using abbot to reproduce the problem 
you see, a simple test case would help a lot here.
