Brett,
I’m very sorry to hear that you are having trouble saving and loading your projects. In order to help resolve this issue, could I first ask you some clarifying questions to ensure I understand the issue correctly?
1. When you say that you “… exit from the analyzer while still keeping my Model Builder program open”, are you closing the entire Model Analyzer app window or pressing the close button on the toolstrip? If you mean that you have closed the entire Model Analyzer app, then could you clarify what you mean by: “the simulation file under the documents tab does not reappear”? Could you share the exact sequence of closing/opening projects and apps?
2. Are you starting with a new, empty project or opening a previously saved project? If opening a saved project, did you have any warnings when loading it? Could you share which release of MATLAB you last saved it in and what were the original contents of the project before you added the simulation program?
3. “I am unable to open later”- can you share whether loading the project gives you an error, results in a project with no contents or an the app that hangs?
4. Does this behavior happen consistently or sporadically?
5. After you save or load and get unexpected behavior, can you share the output when you type “[msgstr,errID] = lasterr” at the MATLAB command line?
6. What is the output when you type “ver” at the MATLAB command line?
7. If you are able to share the erroring project with us, that might help us figure out the issue more quickly.
Again, I'm very sorry that you are encountering this frustrating problem. Thanks for taking the to reply with more information so we can try to resolve the issue.
Best,
Priya
