[Wine] Wine window not maximizing in Mac OS X

[PhilTickelson]

I recently got a new macbook pro 13", 2.4 Ghz, running Mac OS X 10.6.3. 

I am having trouble maximizing the Wine Desktop window that opens when I try running applications. It could be possible that the Wine window can't be stretched or made any bigger, but I'm not sure. If I try to make the window bigger by dragging the bottom right corner, the window gets larger, but it just adds a blank white space. The green + button is grayed out in the window which makes me think that this is as big as it gets, I'm just hoping there's a workaround. 

Thanks for the help.
