Pop up flash not popping up.

I've already got this figured out. Just thought I would share my new found wisdom with everyone. I have a Canon EOS 40D and I got one of those little cover/protector things to slide into the hot shoe. Makes the camera look finished and supposed to keep dirt and such from messing up the hotshoe socket. Well the other day I needed to use the flash due to low light conditions, I could not get the darn thing to work. Refered to the manual and checked all the settings, still no flash. When looking at the menus I noticed that there was an indication that there was an "Unkown External Flash" on the camera. I scratched my head and wondered how this can be. There was no flash on the hotshoe. So I removed the hotshoe protector and surpise the pop up flash was now working. Careful inspection of the hotshoe revealed a tiny little switch that gets depressed by inserting the cover or a flash into the hotshoe.
So if anyone else has this problem this is what to look for.

I first noticed this issue when I looked at a bunch of covers and foung three different designs, the full cover, a cover with a semi-circular notch in the front edge and one with one of the rails cut back about 1/4 inch.
Before putting a hotshoe cover on a camera, check for micro switches under a rail or as part of a push pin on the surface.
Thank goodness for swedish files. You can usually modify a standard cover to work.

I did the same thing a while back,and thought I was dumb, so did not share. I am wiser now and thanks for sharing. Gary

I see it as more of a safety measure than a problem...

I don't want to start a fight, but, it sounds like a Canon problem to me. I have used hot shoe protector as well as a little bubble level that slides into the hot shoe on my Nikon D70, D80, and D90. The pop-up flash works on all three when the hot shoe is covered.

I do not see this as a "Problem". Simply a little switch that keeps the popup flash from trying to operate when a shoe mounted flash is in use. NO-one would even know that it exists if a hotshoe protector was never used.

It does NOT appear in any of my Canon bodies with pop-up flashes I use the polycarbonite hot shoe levels all the time, and my 30D, 60D and 7D (all with pop-up flashes) are unaffected.

I don't have a 40D, but... I think there is something else involved. I suspect that the cover used is conductive (made from aluminum perhaps) and it is fooling the camera into to thinking there is a flash of some design attached.

Here is a photo of the hot shoe on my D40. You can clearly see the plunger for the switch. It hides under the spring part.
