Just lately it seems that whenever I do anything with large files (such as opening a picture from my digital camera in Preview) the Finder starts hogging the CPU and won't stop until I relaunch it (this is even after the file in question has been closed). I tried running fs_usage in the terminal and got the following output:

Code:

which seems to show that it's accessing something but doesn't tell me what it is. Even deleting the file I just opened and closed doesn't seem to stop it. It just continues to hog the CPU until I relaunch it from the Force Quit dialog.

Anyone have any ideas as to what could be causing it, and what else I could check to find out what file is being accessed?

This is on a 500MHz Pismo with 384MB running 10.3.2

Looks like it may not be anything to do with opening the files. Finder doesn't seem to like generating item info and icon previews for 2304x1712 pictures. Strange that it should continue chugging away when the folder is closed or the files deleted, though. Is there any way I can find out what file it's accessing to cause the high CPU usage?
