I have a new Windows 10 computer, and use Windows Live Mail for my e-mail.  When I am reading through an e-mail, if I do not click on the scroll bar soon enough, the scroll bar disappears!  I have to move the mouse off of the scroll bar, then back to where the scroll bar *should* be, and then it reappears.  I tried asking this question once before, and someone wanted a picture of it.  I took a picture of the missing scroll bar, downloaded it onto my computer, then uploaded it onto the web site, but I never heard back from them.  Can someone please help me?
