Hi, I don’t know if you can reproduce this, but I seem to have an issue that popped up at around the same time as the new VorpX updates. Whenever I have VorpX attached to a game and I tab out of it then in again, the ALT key behaves as if it was being held down, preventing access to the VorpX menu and unintentionally activating hotkeys, this is worked around by pressing ALT again once inside the game.
The keyboard handling has changed recently, which saves a quarter of a millisecond (every bit counts!) per frame. There seems to be some odd glitch in the new code that leads to the ALT key being stuck occasionally. I have that on the to-do-list.
