I'm using Visual Studio 2010 Express for Windows Phone. I've been using it for a few months without any problems. About a week ago, it stopped saving my open tabs when I close Visual Studio. The next time I open the solution, it does not automatically open the files I had open when I last closed the solution. I'm not sure why it stopped working and I can't find the setting that controls this. Has anyone else run into this? If so, how did you get it to remember your open tabs again?
I was never able to fix it, but a fresh install works correctly.
