Shutter locks when using the camera in AV mode.

EOS Rebel T3i - Shutter locks when using the camera in AV mode.  It actually freezes up when in this mode...no it's not just allowing more light in through the shutter but rather locking in the open position.  How can I resolve this? Thank you.

Does it do this in bright sunlight at the lowest f/number?

How do you know the shutter is locked open?

Does it do this on multiple lenses?

How long does the phenomenon last, and how do you stop it?

Do you end up with an image? Is it totally overexposed and motion blurred?

Positive it is not mirror lockup?

Why do so many people say "FER-tographer"? Do they take "fertographs"?
