Visual Studio 2008 problems. Breakpoints and crashes.

For the past week or so I've been getting weird problems with Visual Studio 2008.

• "Could not load breakpoint" - This was a mere nuisance really.  Just a few error dialogs when I loaded our solution.
• Completely locks up when closing solution, does not save environment - This started happening a few weeks after the breakpoint issue.  Amazingly annoying, since every time I load Visual Studio, I have to set the right startup project, set breakpoints, etc...
• Closes without an error message when starting 2nd debug session - This is when I got annoyed enough to try to figure out what was happening.  I was losing productivity having to reload and reset my environment every time I wanted to start a new debug session.

Luckily, I found a solution rather quickly.  I don't have the link anymore unfortunately, but all of these problems were fixed by deleting the .suo file in my solution folder.  That kind of a fix should have been obvious to me, but I'm just happy to be back to 100% productivity. :)
