Chrome extension wants to open DT2

I recently installed DT3 after using DT2 (Pro Office) for many years.

Whenever I activate the Chrome clip extension, however, it tries to open Pro Office. That’s the case even if I remove the extension and reinstall it. How can I get it to launch DT3 instead?

Do you still have Pro Office installed? If so, you shouldn’t. Remove the application from the /Applications folder and reboot the machine.
