@oopsowl I’m running into the same thing. New to the app, just trying to get a workflow in place, and GoodTask is my task manager of choice. It just clicks for me. And I’d love to solve this issue. To describe what I’m seeing (which sounds like what you’re seeing) is: (1) I press cmd-shft-space and launch hook. At the same time the GoodTask details panel toggles away and in Hook, I see “No linkable item found in hook.” I’m not too handy with scripting, but I suspect that cmd-shft-space may be a keyboard shortcut in GoodTask that toggles the detail view.
Oh, and given that this seems to be using UI scripting, if the details panel is gone, the UI scripting probably fails. Continuing my investigation.
