Thanks Pixel Pirate!
Kinda annoys me that I can't do what should be a simple thing. I'm finding a few things in SS that don't behave properly and its getting in the way of what could be a really good piece of software.
This sort of thing forces all skins to conform to a particular layout, which surely limits how original a skin can be. I hope they fix it soon, this and transparency in Programs menus.
cheers
