Well that was a quick fix. Thanks ever so much Haris F1. I really appreciate your extremely rapid help. I'm such a luddite I may never have worked that out for myself.
I can actually go to sleep now

Hi there
I'm wondering if somebody can help me out please. I have been handed a RICOH pentax K-s2 for work. It has been working fine until today when it suddenly started overlaying a ghost image of the previous photo on the lcd display when taking the next photo. This itself would not be the end of the world except that the subsequent photo actually ends up being the amalgamation of the the two images. If i review the first image then return to the lcd display the ghost image has gone but it does not go of it's own accord.
Does anyone how i might be able to fix this?
Many thanks in advance
Ben
