First, I copied TGS.gau to gauges folder. Then I added TGS gauge in NGX's panel.cfg as stated in the manual, and this is how it looks like in my case when replaced Fire Protection Panel:
window04=TGS
[Window04]
Background_color=0,0,0
size_mm=100,100
window_size_ratio=1.000
position=7
visible=1
ident=5000
window_size_ratio=1.0
gauge00=TGS!TaxiGuidanceSystem, 0,0,100,100
After starting a flight and receiving taxi instruction from PF3, I press Shift+5 to open TGS gauge panel and P3D crashes right away with some sort of StackHash error.
What can be wrong?
