While manualy or semi manual stitching images, both images rotate for unknown reason. This happens for no apparent reason during the first or later images in multi image panorama stitching work. Cannot get images to straighen out. Stuck...

I'll explain what I think is going on, but I can't be sure without seeing your photos. If my explanations help, great! Otherwise, please contact email@example.com for individual customer support. We'll probably ask you to send us your stitching project so we can see the same thing you are seeing.
Are you stitching hand held photos or were they made with a tripod (i.e. all photos at the same rotation angles)? With hand held photos, you should always use manual stitching. Semi-automatic stitching will usually give lower quality results with hand held photos.
With either method, as you place stitching points, The Panorama Factory adjusts tilt and rotation angles to find the best point match. Sometimes it does make kind of strange choices.
If you're stitching with semi-automatic stitching, this should settle down as you add points to more pairs of images. In other words, The Panorama Factory usually makes more accurate choices with more data. Note, however, this advice applies only if you used a tripod. Semi-automatic stitching assumes all photos have the same rotation angles, so it can actually get pretty confused if there is variation in the angles.
For manual stitching, The Panorama Factory is allowed to vary the rotation angles from one image to the next. It tries to make the average angle close to zero, but it can do this only after stitching points have been added to all images. So sometimes the results are a little odd until you get most of the way through the process.
And sometimes, even with manual stitching, the automatic discovery of image rotation may be incorrect. Fortunately, you can correct it using the warping grid in Wizard step 7/9. Refer to Wizard step 7/9 – Preview at low resolution to learn about using the warping grid. This approach will almost always produce the highest quality result, but takes more effort than fully automatic or semi-automatic stitching.
