TFS: no longer auto-checking out files I change from within VS2008?

Question

Has this happened to anyone? Nothing has changed on my system, yet TFS no longer will auto-checkout files for me when I edit them. If it has, what did you do to fix it?

Under Tools -> Options -> Source Control -> Environment, both Saving and Editing are set to "Check out automatically", so I'm pretty confused at this point.

Answer 1

if you restart VS does it fix it? I get it sometimes too, but it's just fouled up VS

Answer 2

I did end up having to "go online" for my solution. What a pain.
