Applications :: Dashboard Not Working On Snow Leopard

For about 2 weeks, my dashboard hasn't been working properly. I've had Snow Leopard on my machine for about 2 months, so it's not directly related to the fact that I put that on my machine, but I'm not really sure what is going on. Most of the widgets are semi-unresponsive, the weather widget still gives me the weather etc., but none of the little "i" buttons work, and several of the other buttons on certain widgets don't work, making many of the widgets practically unusable. It's almost as if the widgets aren't recognizing the mouse.
I've tried deleting dashboard preferences, and then last night I reinstalled snow leopard, none of which made any difference. I also tried using pacifist to re-install dashboard, still nothing. I really don't want to have to do a clean install just for the dashboard, I'm using a 1.83 ghz intel macbook (2006)
