I am new to this discussion group and no technical computer knowlege.
I have a MacBook Pro which is running MacOS Big Sur Version 11.2.3
My Problem: I can no longer display two windows from two different programs on my screen at the same time. A specific example: I cannot display a page from a .PDF document at the same time that I am displaying a page from a different program; specifically, in this current case, from Reunion for Macintosh genealogy family file. It is either or: Just the .PDF or just the Reunion. I had no trouble in seeing pages from two different programs displayed at the same on my screen in the past. What am I doing wrong?
