I am pleased to announce that there is a new version of Public Talks available to download! This edition has an important bug fix for the Modify Talk button.
The picture icon was not getting updated to match the current Has Digital Media setting for the talk. This was confusing for the user because the database did get updated!
This feature is now working as expected and sorry for any inconvenience caused.
You can also upgrade by using the Check for Update feature from the Help menu (if you have not been a beta tester).
