I’ve tried all the suggested things to fix the probelm. Basically, when I click the Add button, it shows under tabs that it’s opened, but it never pops up to where I can see it. I minimized all windows to see if it was hidden in the background, but it’s not. It creates a second hoverable window in the items in the task bar, but when I click on it it disappears. Totally at a loss here. I need to add more cards because I’ve run out of new cards. It’s the same on all decks. I even tried creating a new temporary deck and it gives me the same problem. Using the windows desktop version.
Does that mean that you went through the Troubleshooting Checklist – Troubleshooting - Anki Manual – especially #2, 6, and 7?
