Don’t use Prefs, templates or projects from C7.0.xxx in C7.5.
Seriously, it’s been reported with every release that these cause issues with new releases. Why wouldn’t you 1) Finish older projects in the version they were started in and 2) Set up everything from scratch when upgrading?
Just opened up and loaded a 6.5 project perfectly ,no problem with my c7.0.6 preferences , so I would say to users , try your own preferences first and as a last resort try Neils way
I along with others have told you that the preferences from a solid running c7.0.6 are working as your statement says “DON’T” use , so we have told you they do work , whats trolling in that then Neil ? .
