Re: 650D shutter failure (error 20)

I was on the Carnival Liberty in the southern Caribbean last week.  I decided to take my 650D out on deck (very hot and humid) and take a few pictures.  Shortly after my shutter started continually firing - the whole time the camera was on.  Kind of freaked me out, being on vacation and a long way from home with a camera malfunction.  Took out the battery and mem card, reset all settings, no help - same thing.  Finally went back into AC and camera straightened out.   A day later I did the alcohol through the shutter switch trick, hoping to clean/dry any condensation that might have been in the shutter release switch.  Anyway, it's back to normal.  I realize it's not the same thing as your problem, but thought I'd share.
