I am prompted to save read-only parts/assemblies/drawings every single flippin' time I close one. 

It does not matter if the checkbox for 'don't prompt to save read-only documents' is ticked.  (Why have this tick-box if it is just a lie?)

How can I make StupidWorks/EPDM behave as it theoretically should?  Once you check-in a file, saving is irrelevant and should not be offered (that's kinda why you checked it in).

Frustrated to no end.
