[Wine] How to maximize a hidden application window?

[Wcool]

Sorry for such a newbie question, I can't find anything in the FAQ but it drives me insane:

I installed Wine and run StrongDC (a DC++ app). All works fine.
Now I click on minimize and StrongDC disappears of the screen. 
How do I get it back? There is no entry in the task bar!

I use xfce4 and tight VNC if you need to know.

Thanks for any answer.
