I have my list of e-mails on the top half of my screen, and the contents of the e-mail I have selected appear on the bottom half of my screen.  This is the way I like it.  With the new version, however, on my Windows 10 computer, if I wait more than a couple of seconds, then I have to move my mouse away from and then back to the scroll bar, in order to scroll down another page.  I very much DISLIKE this new feature.  Can you please tell me how to KEEP the scroll bar SHOWING in the message (how to make it not disappear)?
