Looks like you have a good product here. Here are two samples, one done by a competitor, the other with your demo version downloaded a few minutes ago. Both are from the same 4 images.
The competitor image has been post processed using LAB, sharpening and elimination of the ghosts on the ice (which I have not removed from your demo version). FYI, this stitch did have ghosting at the top of the mountain on the left side of the image until manual control points were entered, and the prominent mound on the right as well.http://mk23.image.pbase.com/v3/57/334157/1/51890367.LakeLouiseFull.jpg
Your application rendered this image in less than a minute, and quite frankly, I'm impressed (although it needs some work).http://i.pbase.com/o4/57/334157/1/53484847.PanotoolsDemo1.jpg
To be fair, I read none of your instructions and stumbled through command sequences to create the image using your software in a few minutes, so information on how to really fine tune it will be welcome.
