I've searched and searched for this and couldn't find anything so I'm going to guess that is once again, operator error. But, for whatever reason, I cannot get JA + Tiger to Force Remake. Doing so yields an immediate Preview window and changes made did not occur. I've tried editing images or changing comments but nothing seems to trigger the remake.
Are you really doing a force remake?
If so, hold down the Alt/Opt key and click on the preview icon, that will open the album in your default browser. Still not sure, try opening the output folder and check the modified time.
Yes, I am certain that I did a Force Remake. Shut down JA, did a few other things, fired it up again and did another. This time it worked. (I had done this twice before with negative results.) Tried the same thing on my other album and it worked normally. I don't have a clue but for now, I guess I'm back to normal.
