I'm not sure what menu button I touched by mistake, but my pop up flash has been disabled. It is even greyed out on the menu screen not letting me access it. I gave up, restored the camera to factory settings and was able to get the pop up flash to work again. The only changes I made originally were to to the sound/beep function; I placed it in total silent mode. I also switched the function of "use camera without lens" option to "on". However, even when I switched those two items back I was still not able to access the flash in the menu. I even tried accessing the flash menu in different setting (A,P,S,M and even iA) but no flash. It was only when I reset the camera to factory settings that I was able to get the flash to work again. I read through the PDF manual but it was of no help. I need help on this. I hope my camera isn't defective as I really like it and would hate to have to return it!
