[Qemu-devel] WinXP mouse patch

The following patch against the latest CVS (13 april) resolved
for me the slow mouse movements in WinXP. It removes from the
datastream dummy mouse-events that contain no movement or
button-change. This is probably the same problem as in Win2K.

to apply the patch:
save attachment
cd qemu/hw
patch -p0 < /path/to/pckbd.diff
cd ..
make

Happy testing,
Mark.
