SD 2.3 preview is crashing when starting navigation mode, the "Start GPS" button in the upper right corner, to be clear.

It happens on Windows XP sp3 32 bit, I'm using SkyDemon on my netbook.

The crash only happens with the real GPS input, the simulator works ok.

This is a regression, it didn't happen with version 2.2.1, that worked fine.



Here's the crash info:

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************

To enable just-in-time (JIT) debugging, the .config file for this

application or computer (machine.config) must have the

jitDebugging value set in the system.windows.forms section.

The application must also be compiled with debugging

enabled.



For example:











When JIT debugging is enabled, any unhandled exception

will be sent to the JIT debugger registered on the computer

rather than be handled by this dialog box.

Thought I'd check this out & can confirm the same results.

Testing by using GPS input from FSX (HW Virtual Serial port & Fsx2NMEA, credit to col-lucy )

As soon as SD GPS is enabled on the PC, SD crashes with the messages shown by iva

Max.

Thanks for this report, we'll get it fixed and post a new beta later today.
