T42P: UltraNav control panel tweaky?

[Marc_G]

Hi folks-

Some of you may have noticed my topic searching for scroll wheel emulation. As part of my playing around with that, I've been in and out of the Mouse control panel, particularly the UltraNav page, a lot today. Half the time I go in there, it crashes, with a Rundll32 error. I have to logoff/logon in order to get back into that window and have it respond.

Any thoughts as to what might be going on here? I think I noticed something similar with my old T30.
