Maybe a month or so, Windows Magnifier on both my work computer and my home computer developed a problem. When I start my computer, and get to the Windows desktop, clicking on the Magnifier icon that I have pinned to the taskbar does nothing. Technically, it shows a horizontal line over the icon for a moment (my taskbar is at the top of the screen) but does not start. This goes on for a while. I have to be in Windows using applications, like Firefox, for about ten minutes before I can make the magnifier work. It used to start immediately. I don't know what's wrong. I can only assume it was a Windows 10 update. I have no idea how I could do that myself. Recently, my boot loader disappeared (again, a Windows update, I assume) and my system had to be wiped and rebuilt about three weeks ago. It still has this problem. How can I fix this? I really need the magnifier to read anything on the screen, and I already have a lower-than-recommended resolution. Thanks.
