How do I minimize Cabal?

After I log on Cabal, there's no way for me to minimize it *I think I did do it once after hitting the keyboard like crazy**
I notice that Cabal is not on the process list so I figure it is running in the background(some rootkit shit).
Is there key i can hit to minimize Cabal Client?

alt + esc

you can put it in window mode makes it easier
