Hey,
I have an unusual problem with my keyboard and the game controls. it seems likely it's just be wonky hardware, but, I'd like to post it and see if anyone can suggest something that I could do to determine if this is the case.
Anyway, I have an unusual problem when multiple keys are pressed. For example, if I am pressing a key to thrust or fire, and simultaenously press and release a key to steer, it seems to register as "two" movements (i.e. the ship or lander will turn two nicks in that direction). If the first key is released, then steering is normal. This is very noticeable in either the melee or while controlling the planet lander, as it makes it very difficult to point the ship in the desired direction. You think steering the lander around after the speed upgrade is hard? Try it when you can only point the ship in 8 directions. :-/
This occurs if any other key on the keyboard is pressed.
This is with 0.3, Windows XP.
This is with a wireless keyboard of mine. On a hunch, I swapped it out for a regular keyboard, and the problem went away.
I wanted to compare this vs. another application to see if it's just some oddity with the keyboard, but I don't think I have a program that would respond in a similar way as uqm does to the keyboard. If I try to scroll in one direction in a document, for example, and then press and release another arrow, it scrolls one "tick" in the new direction, not two, but then stops scrolling in the original direction.
Any comments/suggestions?
Thanks!

Good day,
Thanks for your reply, but, this isn't the infamous key-jamming issue, it's (appently) something different.
This is not related to any combination of keys. Like I said, if I press any other key-- ANY other key- down on the keyboard, steering both left and right is done in two-tick imcremenets. In Melee, with two human opponents, they are both affected, regardless of the controls I configure for them. Your suggestion to use different key combinations will clearly not help here.
I realize that it's easy to just say "It's the hardware's fault", and certainly, that's still the most likely cause of this problem. I am just asking for ideas on how I could verify that the keyboard is sending two keypresses in this case when I have only pressed it once, OR, if the keyboard is just behaving in a way unexpected by the program which could be fixed or worked around (depending on where the error lies).

Heya,
Thanks for the update.
The machine is a AMD XP 2100+. I have some other slower machines that I could try it on with other OSes, so I'll do that before posting a bug, if you think it will help.
