If you have an NMEA feed connected to a COM port (virtual or physical), Windows might detect this as a serial mouse, which causes mayhem. In order to prevent this, before you connect your NMEA stream, do the following:
- Open regedit
- Navigate to the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\sermouse
- In the right pane of the Registry Editor, select Start and change its value to 4 to disable serial mouse detection at boot time.
- Reboot
