I have experienced this behaviour under linux, too. However, all panos affected by this had one (ore more) serious flaws that lead to obviously wrong control points. I seem to remember that all hand held shot multi exposure HDR panoramas using stacks that I forgot to unlink have been affected. As I did not see much coverage of this issue on this mailing list, I have taken that as a hint to invest more time in my shooting techniques and to never forget to use unlinked stacks only if shooting hand held 8) .
b) would it be possible for Optimise to make some sort of check either initially or between iterations, perhaps something like:
There already is some termination condition in the algorithm, I think. However, my very bad panoramas did not trigger it in due time, so I had to cancel the optimization manually.
However, I strongly support the notion to add another termination condition for pathological cases based upon number of iterations or time spent in the operation in relation to the number of pictures involved. If this time out value was user controllable, it even could be adapted to the skill of the photographer or the complexity of the scene.
c) As well as a "Cancel" button could the Optimise running-commentary pop-up offer an option "Stop after current Iteration" which would tidy up the processing and update the control point distances at the end of the current iteration rather than abandon the work done so far ... which is what I assume happens with "Cancel"
I may be wrong, but I seem to remember that cancelling the optimizer run did let you continue with the results achieved thus far.
