I was getting this dialogue literally every time I saved a document, it was maddening. I began shutting down all external resources and programs one at a time and I did, indeed, narrow it down to Suitcase Fusion 3 (14.1.1). Detailed fix: Open Suitcase, go to the "Suitcase Fusion 3" menu item and select "Manage Plug-ins..." Uncheck all plugins for Photoshop. Suitcase should remove the plugin, but, just to be sure, go into the Photoshop application folder and into Plug-ins/Automate and make sure Suitcase's font management plugin is not in there. If it is, delete it. Restart Photoshop (important! you won't see the change unless you do this). If you need fonts activated in Photoshop, after deleting the plugin you can go into "Suitcase Fusion 3" > "Preferences..." and add Photoshop to the "Auto-activate fonts for the following applications:" list. This seems to auto-activate fonts succesfully without the plugin. In fact, I have absolutely no idea why you need the plug-ins, I've removed them from all Adobe apps and added the apps to the auto-activate list instead and it seems to be working famously. Hope this helps some of you. And thanks to everyone who came before me in this thread for helping me solve the problem! FOLLOW UP It seems that if you don't have the plugins installed and you restart your computer, you'll need to open Suitcase once before programs will activate fonts. Minor inconvenience compared to those caused by the plugins, in my opinion.
