I'm running an application on my Macbook Pro. Since yesterday I can't see the application's main window. Its icon is showing in the doc and its options are showing in the top menu bar on the desktop. The program is running normally in all other respects as far as I can tell (it's an audio sampler which I am triggering via an external pedal, so I can tell its working).
The window did show up once in Expose but now it is not showing up there either (no idea why). I've tried adding the application to every space in 'Spaces' and also removing the preferences file but neither of those helped. I have also re-installed the application.
How can I "find" this window?
