alt lock and direction pad weirdness

[bigillz]

I've run into 2 keyboard issues lately-

Any time I press either ALT key once, it turns ALT lock on. I need to press it 3 more times to get ALT off. This happens consistently, every time, with either ALT button, indicating it's a software issue, not hardware.

Another random keyboard quirk, my directional pad works to press once, for any direction. If I press and hold though, it just moves 1 space / registers 1 press for that direction. It has lost its hold-to-repeat functionality. All other keys can press and hold fine, but none of the directions work that way anymore.

Anyone experienced this? I hesitate to wipe/reinstall for this, but it's getting annoying.
