I'm just wondering if anyone know why my thumb mouse buttons won't work in the game.
I have a Logitech MX700 cordless.
The game insist that I'm assigning ALT key when I try with the mouse buttons (just the thumb ones, left & right works fine).

I have exactly the same problem...
I'm afraid there's no way to reslve it...:(

Here is how to fix it guys.. the problem is not the game, but the Mouse setup program.

Go into the mouse setup program in windows and change the side buttons to PageUp and PageDown.

Now go into JA (or JK2) and take the functions you were having trouble with and change them to PageUp and PageDown.

For me it was Change Lightsaber Style (left side button) and Lightsaber (right side button).

You'll have to change the buttons in the Mouse setup program back to browse properly, but in JA it should work fine now.

Thanks Kurgan!
I'll give it a shot... (it really pisseed me off not being able to use the buttons on my mouse).

My logitech software lets me set what the middle mouse button does. I just set it to "Middle Button". That way when im in my games and assign it, its assigned to mouse 3 (or mouse 2 depending on whether it starts at 1 or 0).

This way you'd still have your page up and down buttons ;)
