it's not really the kind of bug that can be blamed on your computer i don't think..
though it would be nice to see if a reboot fixed it..
i am really curious what could be causing this though..
when you click on the last image, and nothing happens.
what does the status bar show?
does it say anything about "loading, loaded, etc.?"
once you remind me the answer to this i think i may be able to narrow down the problem.
will be quite interesting to hear what this turns out to be..
