Some guest being told they already rated image.
I've got image rating allowed for guests on a specific forum. Some of the visitors are being told they already rated the image when they haven't. Needless to say this worked OK when I tried it as a guest...
I'm doing research to find out if they got cookies enabled and/or might be on a changing IP address.
Lastly, this is on RC3 as I didn't want to change things in the middle of the contest we're running.
