InDesign 2021, up to date. New 8.5 x 11 doc, .75 margins. My text box, which I had already placed on a master page, comes in way too small on the first page, 1st screenshot. When I click on it I get the 2nd screenshot - pasteboard shrinks.text box gets huge.
I'm using a MacBookAir with an external monitor, and that's where the problem is, I find. If I work on the laptop's screen it's OK. But I've been using this computer with this monitor since last year with no problem. Just wondering.
