Bill, I saw your question about the upload icon after you installed IE9. I went to my page using IE9 and had no problem. Have you updated or re-installed Adobe Flash? It should be version 11.1.102.xx . This may help fix the issue.
none of my images are more than one exposure apart from when i composite when using two entirely different lenses - i've just bought a new tripod for bracketing multiple exposures so i'm eager to try HDR, but i'm not keen on the over processed look so i'll just go for the extra dynamic range i get..
