You're probably getting tired of hearing this by now, since
it's at least the third time I've reported it, but there is
still no support for serial Kensington Thinking Mice. They
really do exist, I swear!
At any rate, whether doing an X-based install or text-mode
install, there's no option to select serial Thinking Mice.
There's one for PS/2 Thinking Mice, but obviously that
doesn't work if your mouse is actually on a serial port.
This issue has been assigned to a developer for further action.
As of RH 6.2, this *still* isn't fixed.
Kensington Thinking Mice have been added to the mouse list ... you should see it
in the next release ... thanks for your report!
