I have this persisting issue where when i put my mac (snow leopard) to sleep on my macbook, whenever i wake the mac, everything is fine besides the Finder.

The finder does not open up, none of the folders i click on (via desktop) open up, so ii end up killing my finder via activity monitor and it then resets my folder settings ( i have snap to grid and large icons for example).

Whats going on and why is it doing this?

Thanks in advance guys
