I have Bluebeam Revu Build 21.4 installed on my laptop. Recently I've noticed that sometimes when I try to split screens on other programs, like email, Revu will freeze. I won't be able to pull up the Revu window, and I have to close it and reopen it for it to work. If I hover over the Revu icon on the taskbar, it shows a black screen for the preview instead of a preview of the pdf I have running. It's not a consistent problem, but it has happened to me 2x this week, so it is frustrating.
Thanks,
BM
