I updated to Safari 10 and my Paragraph and Single Word Translation is not working
The paragraph and single word translation in Read&Write for Mac uses Flash, for the Sierra update Flash is disabled.
To enable Flash so the translation works please do the following:
1 .Open Safari and at the top of the window click on Safari and select Preferences.
2 Click on the Security Tab and select Plug-in Settings as in the picture below
3. You should now see a window that looks something like the one below.
4. Change ‘translateuk.texthelp.com’ ( or 'translateus.texthelp.com’) to ‘On'.
5. Now select Done
