Hi, @linuxgurugamer i can replicate the bug with the disabled buttons.
KSP 1.7.0+Making History
Action Groups ReExtended 2.3.4
Click Through Blocker 0.1.7.1
Toolbar Controller 0.1.6.29
I started a new sandbox game, entered VAB, placed a kOS processor (doesn't seem to matter what parts i use) and switched to action groups with the stock button, showing me the AGX menu and disables most other buttons.
Then looked for the Script Trigger in the action group menu that should be there for kOS and did not find it. Then clicked the AGX button, which switched everything to the stock action group menu.
After that i left KSP.
I actually migth have to seperate bugs, the disabled buttons and the missing Script Trigger (which is more problematic for me, because i want to use this for my kOS scripts).
I might be able to set up a debugging enviroment, if i find an explanation on how i do so, and give you more info about what is happening exactly, if you can point me in the right direction (i have some experience in c# programming, but not in KSP context).
