Trash freezes


This problem just arose after I had to have my 4 week old computer's hard drive replaced due to a recall. I should have created an image, but thought since I didn't have a lot on it yet, I would just re-install from the disks that came with it. Since that re-install, there have been several minor issues that I have gotten resolved, but this one won't go away. When I try to move things to the trash, it often freezes with a little window with a progress bar running that can't seem to be stopped or turned off. I have to force quit and re-start the Finder in order to stop it.

Would appreciate any suggestions.
