Hi, is there a way to make the client minimize from taskbar icon?

I have The Bat icon in the Win7 taskbar, obviously great for starting the client, with every program I start from the taskbar it's possible to click the icon again and it minimizes the program but not so with The Bat.

Why is this and can I fix it some how.

Sounds daft I suppose but it's very useful for me.

Thanks.
