First off, thanks again to the Photosynth Team - great stuff. I haven't synthed anything in a while, and when I tried again last night, I noticed that about 10 of my photos were "left out" of the synth. The first time this happened, it said my photos were 93% synthy. I deleted that synth, and tried again. The second time, it finished with 74% synthy - but skipped different photos. I tried it two more times, with 74% each. If you look at the un-synthed photos, it's obvious that most/all of them should have synthed... but they didn't. If nothing else, many of them should have synthed with other skipped photos. Its the first time I've seen it skip photos that were so similar.
