I installed Hookmark 7 but as soon as I call Hookmark and select an action (copy link, create new note, create new pdf) Hookmark stops reacting. I was able to create a new PDF with Hookmark but afterwards it stopped to work. I could not even active the application window with control-H or the menu item. I had to force quit Hookmark and restart it. But afterwards the problem happens again. I reinstalled Hookmark 6.13 and everything works fine again.
the problem arose with any “hook to new …” command as long as the option “Enable bookmarking to this software” was active for Devonthink (under services).
Now I deactivated this option and Hookmark works seamlessly again as expected.
