For some reason, some keyboard input don't register with my keyboard in this game.
For example, when I press 'A' for attack mode, it does not register.
But if I press 'Esc' it does register and performs accordingly.
I am using Windows XP.

I wonder if anyone else has this problem and knows how to fix it?

It's pretty frustrating to always use the mouse to open the quick dialog and select attack.
Also opening the inventory from the lower right in the UI is a pain.

Does the keyboard have special drivers or are you just using the ones windows comes with?

Would that make a difference?Well, it does use the IntelliType and IntelliPoint drivers that are a bit special I think.I just tried with IntelliType disabled and it didn't fix the issue...

It really takes away a lot of the gameplay if I'm unable to use keyboard shortcuts.
Don't like to play the game at all. =(

Are you using the basic qwerty keyboard setting?

If its only PST that its not working in, I'd tend to think its the game. It might even be something really simple, open up the config and check to make sure that the keys are actually bound to functions. If they seem to be there, try binding attack to an unused key and seeing if that works
