[Cuis-dev] Space is low

Wed Aug 7 16:46:11 PDT 2024

Thanks so much for working on this issue!

I do the same thing as Jon. I launch the image on my laptop and it always
opens on that screen. Then I move it to my 49" monitor and make it
full-screen. I do all my Cuis work there and save the image there.

I'm using the updated image now. I'll report back if I see the issue again.
Hopefully it's fixed now.
