SegaXtreme

Not all pictures, but quite a lot of them (just get the old empty box with the red 'x' in). If I right click and choose 'Show picture' it works just fine, but obviously I shouldn't have to do that. I'm on XP, and the only thing I've recently changed on my system was reinstalling Norton but I can't seem to figure out a way to fix this by trial and error.. Probably really obvious.

Hope someone can help
