Classical Guitar Repertoire Part 1.dorico (863.3 KB)

This project appears to open, but the window doesn’t appear. All other projects open as usual.

It opens fine here. Do you have multiple screens connected, by any chance? Off the top of my head it may be that it’s gone to whichever screen it was last shown on…

I’ve just changed a note and changed it back (in order to give it something to save), then resaved with a different file. Probably overkill - changing the filename would probably do it.
Does this one open correctly?

That’s the problem. Thank you. I had disconnected the 2nd monitor because it’s resolution wasn’t enough, so I hadn’t considered that.

Good troubleshooting!
