Welcome Flash,
Glad you can finally post.
Yea, I was told a long time ago that the RV devs were going to fix it so the mouse would leave the main monitor, but I have not kept up on F4 at all.
I have an IL2 buddy who flies F4 also. He doesn't use TB yet because he said there weren't any graphically good profiles for it. So, I had to make him look again. There are some great F4 profiles, he just didn't seem the for some reason. Too bad the don't work with RV!!
