Hi John,
thanks so much for your kind support in this case! I do appreciate this a lot!! I redid the whole procedure. Logging events has been activated during my first log file. I jus wanted to keep it short. I have attached a log file (FSUIPC7_Keypresses.log), which was created during pressing ALT+1 until ALT+0. Each Keybinding stands for a different camera I want to switch through.
I also created a different log file, which was created while pressing the virtual buttons on the virtual joystick. I will attach it to the next comment, as I'm limited here with 18 kB max. upload. I checked the file, but for me it seems that nothing has been recorded, but while pressing the buttons, the cameras switched. So, the buttons were working.
Cheers,
Chris
