MBP finder issues 10.6

Ever since I've been running snow leopard (since day 1) I've often run into problems where my finder will freeze up when trying to eject a disk, or browsing through folders in my iDisk. When I go to force quit and relaunch finder, it never comes back up and I have to hard restart. Has anyone had similar issues?

P.S. it's a pre-unibody intel MBP, 2.2ghz with 4 gigs ram.

No one else has experienced this?
