Thread Being Stopped

While debugging a threaded VB.NET application, I got this annoying error:

"Thread being stopped".

A little bit of Googling led me here, which in turn led me here. The problem was with me watching a control on the main form. which apparently pisses off the thread and it goes to it's little corner to sulk, causing the whole system to hang. After I removed the item from the watch window the application worked fine.
