Has the manual alignments scripts been played with or stopped very recently ? I raed there was a mention of reworking or doing something with manual alignment.
On a updated (yesterday) FS version the "manual" alignments button has a different placement in the GUI to a previous version and now attempting a manual alignment the scripts all load and the three boxes (Alignment, faces, instructions) flash up very briefly but then close with no error message, just a "process terminated" !
A complete reinstall of FS does not cure it. A restore of the OS from a backup done some days ago, with obviously a older version of FS, does work.
Using a second slower PC with a FS version that has not been updated recently, it all works as well.
Manual alignments is avery useful tool.
