Select any object. In the action inspector select ‘Open URL’ from the drop down list.

The list immediately goes back to ‘No Action’.

Hasn’t worked since v7.3

Sorry to hear about the trouble! I can’t reproduce this issue using OmniGraffle 7.4.

Using the Help menu, please choose Contact Omni to email our support humans. If you have a sample document that reproduces this issue, you can include it in the email when prompted if desired. Hopefully we can get things working as expected shortly.

Thanks,
Lanette
