by I've seen several postings but thought I would drop this for
informational purposes.
I, too, had problems when switching between Windows and Linux on my
Omniview. After reading several postings and trying different
solutions the one solution I've found that works for me is to do the
following:
When returning to Linux after switching to Windows, I hit CTRL-ALT-F1
to switch to console mode.
I then hit CTRL-ALT-F7 to return to X Mode
After which, my mouse works fine.
Hope this helps someone else.
