Air application appears to be running but is only in the "tray"

I downloaded the Adobe Air installer and seemed to have successfully installed an air application. (I have done this on my own laptop, but was doing it on another machine, which runs Server 2003).  The app seems to install fine. I start it up and it places an icon in the tray, highlighted as running, but the app does not appear anywhere.  Right-click and I can click "close", as if it is indeed running. The task and process appear as runniing in the Task Manager. What gives? Why can't I see my app?
