Pdfs close when scrolling on MacBook Pro
On my almost four-year-old MacBook Pro running macOS High Sierra v10.13.6, pdfs will:
not scroll either with the arrow or touchpad; or
open a blank page window.
This is not corrected by closing and reopening the pdf.
I have re-installed Adobe Acrobat Reader.
Thank you.
