Visual Studio Solution Explorer Randomly Expanding Projects

The folders under my solution in the Solution Explorer window randomly expand. This happens everytime I load the project, and randomly开发者_如何学JAVA as I use Visual Studio 2008. The behavior seems to have no real pattern, and it's like it has a mind of it's own. Any ideas on what I can do to keep behaving like you would imagine it should (expand/collapse only when the + or - is clicked on)?

Tools + Options, Projects and Solutions, General. "Track Active Item in Solution Explorer" option. Feature, not a bug.
