Losing the Run/Debug window

Hi

I keep seeing an issue whereby I lose track of the Run or Debug window which is running Mongrel.  It seems to happen when I run unit tests.  For example:

1. Start Mongrel by running Development: trunk
2. Do some work
3. Run some unit tests

At this point when I click on "4: Run", I see the Unit Test information.  Now, I'd like to be able to switch back to the Run view of my Mongrel process but I can't figure out how to do that. Mongrel is still running because if I try and run "Development: trunk" again I get an " Address already in use - bind(2) (Errno::EADDRINUSE)" error.

Am I missing something?   Basically, how can I switch between different running processes?
