Problems with game controls during testing, please help

[Phanixis]

Ok, this problem just appeared out of no where very recently.

When testing any game within rmxp, the system is registering a continual down keypress. So in the opening menu, the cursor scrolls down, and upon entering the game, the character will continual walk down unless up is pressed, at which point he will stand still.

Two things of note:
-This problem only occurs when testing a game. It does not occur within the editor or windows in general.
-This problem occurs regardless of the game being tested, and is likely a problem with rmxp itself, not a particular game.

I have reinstalled the program but to know avail. Can anyone help correct this problem?

Thanks.

Do you ever connect a gamepad, joystick, or any other kind of alternative to a keyboard/mouse combo? If so, try plugging it in, letting it load, and then unloading it again. (If it isn't plugged in) This is because the computer may be registering a phantom input, because it thinks it is actually plugged in. If one is plugged in, check to make sure that it doesn't have any of the keys being pressed while you boot up, and make sure it is functioning properly.
