There is a hotkey action "Debug->Toggles the debugging log window", which was set to F9 for me.
This used to open a window that shows some debug log output, which would show errors from mods, and so on, (kind of essential for mod development), but this no longer seems to work.
I tried mapping this to a different key, in case there was something specifically blocking my F9 key, and instead mapped this to a key that I could see was working in FAF, but no dice. It seems this just doesn't work any more for me.
Does this work for other people?
If not, any idea why or when this stopped working?
