Hi Franz-Josef! I’m sorry about the regression here. I certainly understand how important it is that OmniFocus be a trusted system.
Since you mention using the Clip-O-Tron with OmniFocus 1, I have to ask: have you installed the new Clip-O-Tron 3001 for use with OmniFocus 2? We’ve updated it in several important ways – you can read more on our support pages. If you haven’t updated, you might give the new Clip-O-Tron a try and see if it resolves your issue.
