FWIW I wonder if this is also responsible for the bug report I posted here:

http://lists.gnu.org/archive/html/qemu-devel/2008-05/msg00853.html

Basically after a random length of time from 1 - 5 days, the mouse under 
an NT4 guest goes crazy - a single touch and it goes flying randomly all 
around the screen. Restarting the VM resolves the issue.


ATB,

Mark.
