The BackgroundWorker is currently busy and cannot run multiple tasks concurrently

*sigh*  One step forward, five steps back. 

As in the words of one forum poster:

BackgroundWorker is pretty much "Threading for Dummies" in that it’s an excellent tool to teach a new programmer how to run work on a second thread and is great for simple tasks; but with it’s simplicity comes the price of flexibility.

If you want to run multiple threads, you really need to use the .Net System.Threading class.
