A family of Microsoft word processing software products for creating web, email, and print documents.
I have the same issue with new Surface Pro (i7 - 7660U @ 2.5GHz 16.0GB RAM, x64) running Windows 10 Prof and Office 365. My external monitor is an Insignia, but I have a newer and larger Vizio monitor at work and the same thing happens. I ran the OffCAT tool and it only told me that I needed to update my Office programs (news to me, as I had received no notice that updates were available). I updated and rebooted, but the problem persists. It makes working on an external monitor impossible. It is also associated with spontaneous and absurd resizing of the window (the whole window, including text on the Word tool bars), which is also extremely annoying. I've used this monitor with my Windows 7 Dell laptop for years with zero problems. It's quite amazing to switch to Windows hardware running Windows software and find myself fighting one ridiculous bug after the next! This is just the latest. I always excused these kinds of things as being caused by poor integration between hardware and software from different companies. But apparently, it's just Microsoft.
