Under Tools – Options – Environment – Documents, there’s the option to Detect when file is changed outside the environment.  Under it is the subsequent option to auto-load changes, if saved.

Personally, I can’t imagine working without having the first checkbox enabled.  However, as for the second, I don’t think I’m brave enough to enable it.

If only the first checkbox is checked, then you’ll get this prompt.

Maybe if you are doing a lot of modifying files outside VS, i could see this dialog getting annoying.  But since the option is global and sticky across VS sessions, I wouldn’t want to forget that I had it enabled.  But consider the source, as this is coming from the paranoid tester that I am (was).
