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.
