I know this has been beat to death here. I am bringing this up again because I have never seen an answer to this. I had an assembly open, checked everything out in the assembly. This sub was in it, I opened it and looked at a few things... did not change anything, just looked around.
Now I saved the main assembly, checked all in and closed. Now this sub is still open. When I try to close it, Inventor wants to know if I want to save this.... I don't understand WHY because I just saved it. Of course, I choose no and it closes.
I refreshed the vault browser and it does not show anything in red, but Inventor still wants to save for some reason.
