This article was previously published under Q108586 SYMPTOMS
When you run Microsoft Diagnostics (MSD) version 2.0, 2.0a, or 2.01, your
serial mouse may behave erratically.
CAUSE
This problem occurs when MSD un-synchronizes the mouse during its hardware
scan of the serial ports.
RESOLUTION
Using the MSD /I switch usually allows the mouse to continue functioning in
MSD until you choose either the COM Ports button or IRQ Status button.
To work around this problem, run MSD with the /I switch, or use the
keyboard in MSD. In either case, you should restart your computer after you
exit MSD to restore the serial port and IRQ states.
STATUS
Microsoft has confirmed this to be a problem in MSD versions 2.0, 2.0a, and
2.01. We are researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.
