Self Healing 7D?

I decided after my 7D started showing error 20 last weekend that I’d live with taking my battery in/out for a few weeks before sending it back to Canon for the 3rd time.  It’s prime time at the coast and I didn’t want to be without a camera for another couple of weeks.  Went out on Sat morning and shot around 1200 pictures and it only locked the mirror up about 10 times early during the shoot.  Went out again today and took about 1700 shots and no issues what so ever.  Not sure if it was a fluke or if the shutter needed some breaking-in time.  What ever the case, I’m going to keep using it until the problem comes back.  Hopefully it won’t.  Probably wishful thinking on my part…

Update:  my 7D is still working OK after several outings and several thousand shots.  Not going to send it back again.
