Hi,

I went on to compile dgibson's rep which includes that commit. But the
issue remains.
I normally use -usb-mouse -usb-kbd in the command line, as these work
for Mac OS 9.x up to 10.5. Using -usb-tablet allows the mouse to
travel outside the GUI and seems to circumvent the issue in OSX
guests, but Mac OS 9.x  guests do not work with -usb-tablet.

Best,
Howard
