Vitalize! Game saved by older versions of MMF / TGF played by the latest version of the Vitalize! 4 does not work correctly. There is a problem, the game does not respond to mouse buttons (especially on the left button press). Game saved MMF2 / TGF2 work properly in this case. Please patch it.
A typical space shooter, you can't shoot because the attack is attributed to the left mouse button.
Reinstall Vitalize! 4 does not help. Beta versions of the Vitalize! 4 does not have this bug.
