[TxMt] Spaces and 'mate'

I'm running Leopard and use Spaces. I also use the 'mate' command a lot, often from a different space than the one in which TextMate is running. When I run "mate /filename/" (or "mate /directory/") from a different space, the new TextMate window opens in the space TM is already in and I'm switched to that space automatically. I don't mind that. But the new window opens /underneath/ the existing TM windows. I often have a number of windows open (a couple different projects, a web preview window, etc.) so the new window ends up being completely covered.

Is there any way to change either TextMate's or Spaces' behavior so that new windows get opened in front of the others?
