VS 2008 is randomly opening sub-folders for me. Sometimes just a few, sometimes every sub-folder in my project or solution. This happens even when I am not using it - last night when I knoocked off, my solution explorer was closed up tight - this morning, one large project had dozens of sub-folders open.

This is not a matter of restoring a previously saved state - most of the folders that get opened are not part of the project, and I have never looked at them with VS.

I have downloaded and installed the PowerCommands add-in, and it lets me collapse everything nicely. But I don't want to have to do this several times per day - it closes up folders that I want to be open as well.

So, does anyone know why this happens and how to stop it?

I found this question from a few months ago which is about the same as this one, but was not answered. I am hoping someone has figured out a solution.
