Ah... right. This is a Leopard bug that we've reported. The deal is that OmniFocus adds a child window for the spinning progress indicator to the main OmniFocus window in anticipation of needing it (since we can't add it while the app is stuck saving). Inexplicably, Leopard interprets this as the application needing attention and switches to that Space.

We've logged this bug with Apple, so hopefully they'll address it in 10.5.1. Until then, we'll continue to figure out if there is a way we can do this without annoying Spaces.
