Yippee! I just noticed that this bug - a bug that affected sheets and Spaces in Mac OS X - appears to be fixed in Snow Leopard.

The bug would result in your computer switching to any space in which a sheet appeared or disappeared. It most frequently annoyed me when I'd post via MarsEdit, switch to another space, and get sucked back to MarsEdit because the "Posting…" sheet had gone away.

Party on!
