GTN Freeze Just Flight Turbo Arrow

[zoltar]

I had a similar freezing problem which was caused by starting FRAPS midflight. Very easy to replicate; strat FRAPS GTN freezes.
I could fix it midflight by switching to GPS 530 (it was still working OK), killing the TDSGTNXiFlightSimEXE process, then starting it manually again.
The splash screen came up, I selected the GTN 750 from the tablet again and it was working again.
