Thank you for letting us know. This will be a lot more helpful if you explain what you were doing when this happened, whether this is happening consistently and how to reproduce it, and what you’ve tried from the Troubleshooting Checklist to make it stop.

I was studying a pretty large filtered deck. I had opened the edit window for the current note, and was closing it when this dialog-box appeared. For what its worth, a browse card window and perhaps an add card window too were open in the background.

A simple restart of the application helped. I haven’t tried recreating the scenario, and it hasn’t occurred since.
