I’m running Hookmark Pro 7.2.2 (6644), Scripts version 423.
When I use “Hook to New… > Drafts,” Hookmark switches focus to the Drafts app as expected, but no new draft is created and nothing appears to get hooked. Nothing else happens — no error message, just a silent switch to Drafts with no note.
I have updated Hookmark script server, script version 424. Could you please update your Hookmark script and see if the issue is fixed (Hookmark preference window->Update->Check now)?
