So if you got to my site's archive
http://thorsthundershack.com/comic/archive
And then click on a comic, the image will br broken on loading. Refreshing doesn't fix it, but if you got back and forwards the image loads properly.
I'm using the moest recent Grawlix (this was happening in the release version too), and it happens in every browser I've tried it in.
Any idea what could be going on?
