Stage Preview missing on second screen (mac)

[cyport]

I have a small issue with Isadora. I was using an external monitor plugged in via HDMI to my MacBook to preview the stage window on a second screen. 

Since closing Isadora and opening it without the monitor I am unable to see the stage preview. Is there a way to force the window to open on my main display. I have noticed that the stage preview is somewhere to the right of my screen, outside a clickable area.

I don't have access to an external display at the moment so it would be great to see the stage preview!

A quick fix is to change your screen resolution to something smaller, then revert it back. It can often push the window back down.
