I am working with a .Net developer to create a DLL that I reference from my MS Access application. To help testing, I created a very basic Access 2016 db with a couple of forms and a module that will contain all of the code. However, when I send him the .accdb file, the startup form does not load. Plus, he can only go into Layout and Design view of the forms. The odd thing is that he can open the module and run the test functions just fine (either from the Immediate window or directly).
He doesn't get any security warnings, it's pretty much the same version (slightly different revision), our security settings seem similar (we have compared Trust-center settings and added his location) - but nothing - the forms will not open normally. Also, there are no compile errors.
I'm sure it's something to do with security - I'm just not able to see the fix at the moment.
Any ideas would be very much appreciated.
