I encountered an annoying bug (Mathematica 8.04 for Mac).

The notebook changes its name to "Untitled-1" and all the closed cells lose its information. Then I have to close it and open the last saved version, which is annoying. There is a beep but no message when this happens.

I still haven't quite figured it out how this is triggered but it may have something to do with the usage of a dynamic module. The notebook name is not altered in anyway in the entire notebook.

Did anybody of you encounter the same thing and if so how can I avoid it form happening again?

What exactly is the question? – Mr.Wizard Oct 17 '12 at 8:37
Ok thanks, I added the questions. – gogoolplex Oct 17 '12 at 9:00
Never encountered this. You mention that you suspect a dynamic module, what is that module doing? Manipulate Notebooks? It's very hard to help you with the little information you have given. – Matariki Oct 17 '12 at 10:18

@gogoolplex Could you provide the code? This would enable us to try to replicate the behaviour you experience. – Matariki Oct 17 '12 at 13:47

@gogoolplex I would recommend that you try to reduce the code present in the notebook iteratively while confirming that the problem persists. Then update your question with that code, so others can confirm the behavior. – jVincent Oct 17 '12 at 20:12
