Some very good questions there.

Same working directory as previous
Local
Project Viewer is open - has to be to use F10 etc.
Same desktop as previous so Project View plus 6 Forms open.
No job file.
Changing working directory to another folder with a single query in it 
works just fine.
Changing to directory without anything paradox in it works just fine.
Changing to same directory on another SSD - clone from 2 weeks ago has 
same behaviour. Ditto for one from two years ago.
Windows indexing is on. Nothing has been changed.

So the next thing I am going to try is do a chkdsk although if that was 
the problem the other two drives tried cant have the same issue.

Anyway. Very strange.

Thanks for the suggestions.
