Has anyone else had problems with the popup flash not alway coming up when you hit the flash button on top side of camera. It seems to work about 90% of the time, but at times seems to stick. When it sticks, I can hear a clicking noise like it is trying to release but does not. I can always get it to release if I give it a little assistance. I just had a brand new grandaughter last week so I am hoping not to have to send it off for repair.
