Bad Dashboard Problem

I have a MBP 2 GHz with 2 GB of Ram. OSX 10.5.2 with all my software updated. I have a strange dashboard problem. When I use certain programs like "Web Clip" ,"i Stat pro" or most any other downloadable program from apple it eats up my CPU. It uses my CPU 80 to 90% constantly. WHATS GOING ON? I have uninstalled these programs and installed the newer versions and still having the same problem. Please help, I must have my dashboard back safe and sound.

 

Yes I have done that. Activity monitor is what was telling me about my problem. Even when I'm not using Dashboard, it's still running my CPU to the ground in the background.
