Sorry, we had a lot on our plates for 1.8 and didn't get a chance to look into why there might be a ghost window appearing in Exposé. (Exposé automatically finds windows on the screen, but that doesn't seem to be a window which we've placed anywhere on the screen—so I'm not sure where that's coming from! But it seems to be unique to OmniFocus, so we must be doing something to trigger that bug in Exposé…)
