Color Selection/Eye Dropper problem

Hello, I have been using Photoshop for quite sometime now for basic image editing and website design. I recently upgraded to 7.0 since 4.0 was giving me some trouble with memory errors that would result in loss of work. Anyways my question is this: Lately (as in the past week or 2) I have been having a problem with my Photoshop, when I would click on the color selector (the 2 color boxes in the tool selector box) it would select the Eye Dropper tool instead. And from there I could not do anything without hitting Alt + F4, after doing that the Eye Dropper tool would go away and I would be back where I started, still unable to change or choose a color. While the Eye Dropper tool is active when I do this I cannot click on anything or do anything, the Eye Dropper tool will not even function. I would only get an error sound as if I was trying to do something I'm not supposed too. I've never encountered this before and cannot find this same problem anywhere online. I have reinstalled PS numerous times and still the same effect. Has anybody else had or seen this problem? How can I fix it? Thank you for your time.

Nevermind, I found the problem. Apparently if I run PS with only 1 monitor on I get this error, but as long I have both monitors enabled it works fine. That's weird but atleast it works now.

Yes, plug the second monitor in, move the palettes and windows like the color picker on the first monitor and you should be done. Alternatively, delete your preferences.

CS2 does not have this problem anymore.
