I'm having the same problem. If I change the design to Ribbon Fullsize Lightbox, all is well. But if I try to use one of the slideshow designs, I get the same problem with the first 2 images being shifted to the lower right corner. Then the rest of the images seem ok and clicking forward or back displays images ok. The problem occurs on Safari as well as FireFox. I installed the browser fix but it didn't help. It's a little annoying to get a offer to upgrade for $79 to version 2 when version 1 doesn't work.
