>> I also tried 3DS.PRJ…<<
I missed Martin's post, but if you have a "3ds.prj" in your \projects
subdirectory, 3ds loads it when initializing or resetting the system. BUT, if
you then manually load ANOTHER prj file, the settings in THAT prj file will
wipe out the settings made by your 3ds.prj file.
The only thing 'magic' about 3ds.prj is that gets loaded automatically.
