That's disconcerting. How do you launch OmniFocus? If you're normally running OmniFocus 1.1 (the new, beta, syncing edition) it sounds like maybe you got hold of a 1.0.3 version somehow.
I'd recommend manually getting the latest from
http://www.omnigroup.com/application...ad/sneakypeek/ and then making sure that's the only copy of OmniFocus on your computer.
If you never intentionally ran 1.1, there may be something far more sinister going on here, and I recommend emailing
