Keyboard shortcut gone wrong

I hope no one minds my asking this here, but I was using Photoshop 7 and suddenly something changed. When I have the brush tool selected and hold down the Alt key, i can use the eyedropper to select a foreground color. But all of a sudden, it started putting the new color in the background instead of the foreground color. My status bar still says "Click to select new foreground color" when I have the Alt key held down, too.

Anyways, a long time ago it used to frustrate me when the brush tool became a crosshair and it took me ages to figure out that it happens when I have caps lock selected. (I don't right now.) Someone posted about that earlier here and I thought maybe this would help someone else out too? Hopefully. Anyways if someone could help me out that'd be great.

EDIT: I just had the eyedropper tool selected now, and it still does that. I don't know what's wrong, but I could sure use some help here! *cries* This is odd, has anyone else had this happen? If I hold down the alt key with the eyedropper tool selected, I can select a new foreground color, but it's supposed to be the other way around!
