I cant stop my assemblies loading lightweight.

The odd thing, is that this has become a problem since implementing PDM standard. But  I don't understand how that can mess with my system setttings.

Other system settings do remain as set.

So it seems each time I open solidworks I must re-uncheck that box i have ringed in red? why? All my users have the same problem (2016 SP5.0)

Has anyone else got this enforced blue feather fetish?
