Yo, I've been having the same issue. I think I may have found a fix from someone named zaviero in another thread, but I haven't had time to try it yet:
"Right click the 7thheaven and set and set the compatibility to run as as administrator. apply and close.
Then find the FF7 exe you are using eg.. ff7_bc right click and set compatibility to run in 640x480. Don't worry the opengl plugin will override this anyway.
Next go back into 7thheaven and try launching the game.
This seems to have worked for me going to test on my tab that had same problem."
EDIT: I just tried it, this seems to be the fix.
