Can't get past first creator/company dialog

First time using the MSFS2020 SDK (v 14). Installed and tried to create my first project… and I get an initial dialog which appears to be asking for creator name and company name. I was able to enter values by tabbing between the fields, but there seems to be no way to continue… Enter does nothing, mouse does nothing, the dialog can’t be resized.

OK, I resolved this by switching out of fullscreen MSFS. Once I hit Alt-Enter to go into windowed mode, the dialog became usable and I was able to hit Next.
