Circle and Rectangle annotation figures and text

I’ve been trying to figure out a way to enter text into the accompanying dialogue that appears when I create a circle or square annotation. I can see my cursor as it moves into the “text” square for input, but no typing appears on the black background.

I’ve futzed with changing colors and such, but I can’t find anyway to get text into the text window.

Thanks for advice.

Circle and Rectangle annotations don’t support text, therefore this field is disabled.
