There's a solution basically for the Carenado C90 and C210T but should work with all.
You have to make a XML gauge to do "the no-reflection selection" automatically.
(L:InitIR,bool) ! if{
1 (>L:WINDOWSTINTBOOL2,bool)
1 (>L:InitIR,bool) }
Put this code code into a text file, called IR_off.xml
Put the xml file in a new subsfolder to your panel folder, named Controls
In the first Vcockpit section of the panel.cfg file, add
Gaugexx = Controls!IR_Off, 0,0,1,1
to the bottom (adjust xx to the next unused number)
If it can help... this time.
