Okay, so if I remove test mode. It should help it?
No. Not at all. I never run my install outside of Test Mode. It's too vital of a tool for BC. Neb may know how to change the text on the QB/Test Only button (you guys did it in KM.) Is the name really that big of a deal? You can still access QB, and now more.
Ok, moving on. You say the mutator menu doesn't scroll anymore. I'm not certain what files the patch replaces, but the fact that you decided to patch the game after you started modding it may have had some effect on that. (Mleo, please confirm/correct.)
For the future, when making a new install
always patch the game,
after installation and
before adding any modifications (this includes the Foundation.)
