The process does complete eventually, like i said it just hanges for a long time, once it kicks back into action is proceeds at a pace that I would expect. After the align layers based on content is complete and the blending layers .... starts the progress bars fills to about 1/5 then hangs........ 4/5 minutes later (worst case) then its zipp.. off she goes again. Its almost as is Photoshop has cought narcolepsy and has a spell half way through.
