PS CS3: Color Picker weirdness

I use Photoshop CS3 on Mac OS X (Leopard).

I was working on a photoshop manip the other day when I wanted to change the foreground color. I clicked on the foreground color square and got a shock when the dialogue box looked completely different.

I was used to something like this:


(Image from this website, it's in Windows but with the exception of the top part of the dialogue box, it looked the same.)

But I get this instead:



I've also noticed that the tool will switch to the Eyedropper Tool when I click on the foreground color box, no matter what tool I was using before. The "Only Web Colors" looks like that as well, not like the original version.

Does anyone know what could have caused this? I've never had this problem before, and I don't think I installed any program updates.

Help is very much appreciated. Thank you!

ETA: Weirdness solved. Thank you all!
