Help - resizing program windows seems to be disabled

Hi,

I've looked for a solution to my problem but haven't found one... For some reason, my ability to resize ANY operating program window is disabled. Does anyone know how I can enable this on my MacBook Pro? Actually, it seems I can't even MOVE the windows around on my desktop

ANY help would be appreciated...

 

Thank you both for your comments. I have Mac OS X 10.6.7 version. As far as I know, I haven't installed any automatic resizing programs. It's very frustrating, because I'm not sure what's going on (I can't move the windows nor resize them...). I'm fairly new to Mac, but I figured out how to resize the windows a while back - I don't think this is the problem. I tried turning off the computer, as well, but no luck Any other suggestions?

 

I'm sorry... I don't understand what I should post... a screen shot?

 

This is perfect! It does work with a USB mouse (I can move the screens/windows and I can resize them. Now I have to check everything else you suggested.

Thank you, everyone for your suggestions! I'm going to pursue this "mouse" problem.

 

I've been reading other posts in which the trackpad button fails, and the posts seem to suggest it's a hardware problem (essentially, you either have to clean the interior of the computer or fix the spacing between the trackpad and the computer housing). Is there any SOFTWARE problem (in other words, the configuration one chooses on their MacBook Pro) whereby the trackpad button doesn't respond?

This seems to be my problem... my trackpad works: I can scroll with it, and even click with it by tapping it, and the windows/programs respond as desired. The problem is that the trackpad BUTTON, when I press it to either close a program, or hold it down as necessary when resizing/moving program windows, doesn't "work"...

 

Yes, as I said before, the trackpad works fine. It's the trackpad BUTTON that doesn't respond...
