I have found the same problem. Better results are achieved if
the PS/2 port is used. I have been unable to get any mouse to operate
through the serial port. I have tried various settings and experimentation
with the mousedrv.ini file with 3 different Logitech rodents with so-so
results.
Yes, I think a bug list might be in order, perhaps as a part of the FAQ.
