K100d flash / AF-assist operation?

Surely either the Sigma caused the problem or the K100d caused the problem, one way or another something went wrong with that combination which has now altered the functionality of the camera.
OK it may not have been a high voltage, but if the Sigma did not cause the problem then it seems a very strange (and even more unlikely) coincidence that this problem would only develop during and after using the Sigma...

Or you are doing something wrong. These are complicated bits of kit, and it is all too easy to overlook or misunderstand something written in Japlish.
As you say, it's rather a coincidence that two things have gone wrong at once, but I should be surprised if the Sigma has caused a problem with the camera. If the flashgun were a twisted, smouldering, piece of molten plastic then perhaps the capacitor got shorted and destroyed everything, but the fact that in every other way everything seems to work suggests to me that the voltage is under control.

Probably the Auto Picture mode only uses AF.S so that would explain why it works.
George is right... there are things hidden away in the "English" translation of the Japanese manual that catch the unwary!!
Page 125 of the K100D manual - it doesn't actually say that focus assist doesn't work in AF.C. You can only imply it because it says it works in AF.S mode

Edit: I just realised the obvious answer. A fairly disconcerting thought. The AF assist on the K100d used to work in all modes. I attached a Sigma on which the AF assist did not work, and now the AF assist on the K100d doesn't work... could the Sigma have messed up the K100d's flash? It's certainly possible for overly powerful flashes to completely fry the flash circuitry, so is it possible that a lesser fault could cause only partial damage?
If so this is fairly annoying since I will have to return the faulty Sigma and have the K100d fixed, and both were from different shops.
Thanks in advance for any thoughts.
