I get an error message when trying to open the app in High Sierra. See attached

"Unable to Start Nisus Thesaurus. Error: Could Not Load Thesaurus Manager"

Any recommendations?

Please see this thread: viewtopic.php?f=6&t=6825

Long story short, try redownloading the Thesaurus app and reinstalling it. That appears to clear up the bug.
