If you've been using XNA Game Studio to develop games for Zune, you're probably familiar with the following debug output:

The thread 0x1234 has exited with code 0 (0x0).

This message gets spit into the Output Window while debugging, about once per second, if not more. It shows up so frequently, in fact, that it makes it very hard to see any other output at all!

Since it's pretty rare that you're actually interested in these thread exit messages, seeing them can get quite aggravating. That's why I'm posting this to explain how to suppress these messages from the debug output.

While debugging, right-click on the Output Window, and uncheck "Thread Exit Messages". Done! Now you can use the Output Window again!
