I was on a shoot today and needed some filler light, so I hit the flash button, to pop up the flash, and nothing happened.
When I checked the menu/Flash control/Built-in Flash Func setting the following message appeared: "This menu cannot be displayed. External flash is attached". But it isn't! 
I put to external flash on the camera and removed it again; thinking it might, somehow reset but it didn't change anything.
Is there a menu setting that, if set, would cause the camera to think an external flash was attached, or is my camera broken?

That was it. Thanks!
