Running Flex Unit in AIR

Hi I am loving flex unit and wanted to use it on a air app I developed a few months back.

I added an new application.mxml file to the project and added the TestRunnerBase and a ref to FlexUnitCore.

When I try to debug the app, the debugger starts but the app never becomes visible. I can see the process in windows explorer but can not see the app on the screen. If I take out the reference to FlexUnitCore it runs fine. Of course the tests can not run. Am I doing something wrong or is Air not supported?

Air 1.5

Flex 3.2

Any pointers appreciated.
