A family of Microsoft word processing software products for creating web, email, and print documents.
Basically this is a problem with Office 2013. One of the software engineers at Microsoft decided to time-out the scroll bar use after 5 seconds if there is no mouse motion. Unfortunately, this software engineer has not worked in the world of reviewing documents. We are stuck with this unfortunate decision by MS to both, not-catch this, and never decide to send an update to remove the 5 second scroll bar deactivation.
For my newest computer, I will instal MS 2010 instead of 2013. Because that programming mistake is driving me crazy. But really, MS needs some competition, I believe that's the real solution. I wish I had a way to resolve this issue with Word 2013, but that setting is hard-coded into the software.
