Help SNESOID Keyboard 3 button press issues

[shedfortest]

So i've recently gotten snesoid for my transformer and its great.

However after playing some games i realized i cannot press three buttons at once using the keyboard (ie. running, jumping, and charging a gun). It works fine if i use the virtual keypad on the screen but can't seem to get it to work with the keyboard.

any ideas?

I was just playing Earthworm Jim (for no reason) and was able to hold up and left and press the swing button all at the same time. So it's probably a limitation by the game itself
