Can't set Port in Options (NMEA)

[wingbolt]

I'm unable to assign a Port under NMEA in the options tab. I can't check or uncheck the box either. Any ideas? I used to be able to connect to XCSoar over wifi, but now I cannot without a Port assignment.
Thanks,
Phil LeRoy

I forgot to mention I used to be able to set the Port prior to updating the 2.0.5 patch.

In order to be able to check/uncheck the NMEA tickbox, there must exist at least one COM port on the PC (they maybe seen in the device manager which is updated dynamically)

I made a test with HW Virtual Serial Port, I'm still able to connect to a COM port in the OPTION tab of the SETUP.

However, the port must have been created before you open SETUP (can't remember precisely how it was in 2.04 but I guess it was the same)
