Camera Error on A200

[charinor]

I have a problem with my A200.  When I take a picture the camera works fine mechanically the image is captured on the memory card but on releasing the shutter button I get a Camera error message instead of the image taken, the camera locks up and I can only switch it off wait a few seconds and turn on to go back to normal.  I can see the image on the memory card in the normal way so I know the camera is working from that respect but as I said it locks up as soon as I take a picture.

any help?

I have already tried taking out the battery to no effect.
