VBA developer window on Macbook

Hi,

I'm developing VBA code in Office 2021 on a brand new Macbook. When I open the VBA developer, it shows on my Macbook primary screen. Now I want to move it to my secondary screen. That doesn't work: I cannot move it to any other screen. This typically works fine for any other window, but not for VBA.

MS support cannot help and suggested to post the topic here.

Any clues?

Thanks,

Reinier
