Missing viewport when receiving windows 3dm file

Rhino Rhino for Mac
1

Okay so i sometimes a 3rd party to do some surface work and he uses Rhino on windows. He models with perspective view port on his primary screen only and everything else on a secondary monitor. If he saves the file when still viewing like this and sends it to me to open on rhino for Mac (5.4 WIP 5E397w) it plays up

first attachment is how it is recieved,
second attachment is the missing viewport, simply find by right clicking the rhino logo in the Dock
Now i cannot get back to the standard 4 view ports, i press the button and the third attachment shows the result

Sorry for the delayed reply. Yes, I tested this with the file provided and was able to reproduce this issue in 5.4. However, this bug does not happen in Rhino 6 for Mac…so that’s good-ish news.

Thanks again for providing the file and clear steps to reproduce this.
