I have assembly models where some of the parts within them are loaded read only primarily because someone else in my group has them open already as part of an assembly they have open.  When I save my assembly before closing it SolidWorks always asks me if I want to save these parts even though they are read only (and even thourhg I did not modify them).  I have the box checked to indicate "Do not save read-only documents" but SolidWorks asks me anyway if I want to save these.  What's worse is when I click "Don't Save" it will ask me againand again if I want to save the same parts.  Sometimes when closing a large assembly, I can be asked 10 times if I want to save the same parts and I keep clicking "Don't Save" until it finally closes the model.  Here is the screen I'm talking about:

Am I doing something wrong?  How can I eliminate SolidWorks from askiing me to answer the same question over and over again when I've already told it I don't want to save read-only parts?
