I’m using Windows 11. An odd thing I haven’t had before - a single Dorico file works fine, but when I put the cursor over the taskbar icon, or use Win-tab to display / cycle between active programs, I see 3 versions of the Dorico file. As I say, functionally it appears fine. I’ve saved as a new file, and the same happens.
I assume there is some corruption somewhere, so may eventually export all the flows and re-import into a fresh file, but wondered if anyone else had seen that.
