New Sketch leads to weird menu state

[Travis]

On macOS Catalina, with Vensim 8.1.1:

I have a model open. I choose to use the new Sketch view. That closes the current model (I think). I re-open my model. I then close my model (cmd-w). This leave another blank "new model' window. This window doesn't respond to cmd-W. I click the red close-window button. The menus mostly disappeared with the VensimDSS menu not showing Options and the File menu not showing any of the "Open Recents".
