Hiding Google Desktop on all desktops save last

[rdanner3]

Is it possible to hide Google Desktop on all desktops save, say, the last one?

As a writer, I sometimes need all of my laptop's screen available for various programs. As it stands, Windows Sidebar (I'm running Windows 7 Home Premium 64-bit) hides nicely, while Google Desktop is just... there. Not that this is a huge issue, mind, and I expect it's solvable via the INI file, but my question, I suppose, is "How do I do this?"
