Before connecting up this ground, TX'ing at 100w
on 20m would shut down my computer and on 17
or 10m would lock up my mouse. Now, with a good
ground (I think), everything is OK except if I go above
40w in the CW portion of 10m - then my mouse
sometimes locks up. It's a PS-2 optical mouse.

Now you know the facts - here's the question:

Is there anything I can do to improve this situation?

Unfortunately RF gets both in and out of numerous parts
of the PC. Have you opened up the mouse and checked
for shielded cable, and does it connect to the PC chassis?

In the past I've added small value capacitors to the keyboard
microcontroller board to cut RF leakage. Perhaps the same
type of thing could be added to your mouse. I wouldn't
go more than .001 microfarad to avoid rounding off the TTL
signals too much.
