Aaaaannnnd . . . its broken again!!! 😞
It starts processing the focus stack, then hangs about a 6th into the progress bar . . . and there it sits
in the meantime, Ive switched on my 12 year old MacBook, loaded photoshop, imported the layers, aligned them and focus stacked them, saved back to my server. Force Quit Photoshop on the PC, re-launched it and opened up the stacked file again.
Adobe, there must be a fix for this, its insane!!
