Well, I guess I will get to check out Canon Service.

My Rebel Xt just locks up for no reason I can see.  I thought it was because I was changing lenses, but it happened today with no lens change.  It does come back after a while.  (I haven't figured out whether removing the battery or the card or both helps)

bummer, though I have dropped it a few times so I am not necessarily blaming Canon!

I live about 30 miles from the service center in Irvine which is right on the hairy edge between shipping and dropping it off...

Has anyone else experienced anything similar?
