Bought the 60D only this month. I used it twice already, both using the external 430EX II flash. The problem is when I tried to raise the pop up flash, it wont raise. I turned it off and on several times and removed the battery to refresh the memory but the same thing, it wont pop up. I tried to set the flash through the flash menu but it is saying that the external flash is still attached. i attached the flash and reset the flash setting but still it wont pop up after removing the external flash. Anybody experienced this before?
