Hi Aleks,

as far as I get it, you only have to make sure that your open document is at the default location as Lizard mentioned.

But I read something in the release notes of the last SneakyPeak, that Omni fixed something about not recognizing documents in a non-case-sensitive environment. So maybe your problem is fixed by the latest version ...

Regards
Boris

Edit:
If you open OmniFocus by starting the App and not by clicking on some .ofocus file, it should have the default location.
