Something's not right here.
Every time I open my doc and click inside the InDesign window, the entire window snaps to the bottom of my screen. Half is below the screen's bottom visible cut-off.
I have search for a control to override this, but I can't seem to find one.
Duplicating the doc didn't help and new docs do the same thing. I don't think it is an Apple setting.
It doesn't do this on the laptop side.
I'm experiencing the same problem; seems to have started happening within the last week or so.
