I couldn't find this in the search, so here it goes.
In the past week or so I have noticed an interesting problem with my finder. Whenever I 'right-click' or ctrl + click a file in my finder window or even on the desktop I my system freezes up and then finder crashes and restarts.

I am running 10.3.3 on my iBook G3 800 with 640 MB ram. Like I said, this has just started happening after I updated the airport stuff a few weeks ago, or whenever that happened, and I am wondering if that could be the cause, or if anyone else has experienced this same thing. I am not opposed to doing a re-instal, but would rather not.
Any hints or help are appreciated.
Thanks
