...Not really, it's been proven that people very rarely bother to use a forum search engine prior to just firing off a new thread. ...

I was unaware that this was "proven", but it certainly looks that way - judging from what I've seen, anyway. However, even of you used (say) a site: search (as opposed to the cruddy internal search tool), finding and consolidating relevant/related material in the discussion threads is still likely to be an uphill battle and somewhat hit-or-miss.

DCF is often a veritable mine of useful information, with stuff to be found on various subject categories in DCF discussion threads, but a lot of it seems to be buried in or scattered across threads broken into multiple micro-sub-categories. Occasionally, I try to pull these bits and pieces together into specific higher-level category threads to provide a sort of indexed experiential knowledge-point on a specific subject category that I am interested in. The trouble there is that I am the sole author/editor of the index I created, and - as things stand - it can't be edited in a shared or collaborative fashion by other DCF members. This is a spotty, unreliable and inefficient way of accumulating/curating a knowledge base category.
Ideally, we would use a Wiki for those...    :o

If the Windows Magnifier (press Win and + keys) is displaying a black lens or screen window, then the likely cause is the NVIDIA graphics driver. The fix is to force the magnify.exe proggie to work with the standard GPU - not the NVIDIA GPU.

Windows 10 Magnifier Lens Window is Black

By BGGRIT on 2015-08-13
I have set up my magnifier (size, shape, magnification, and to auto start), but the lens window will randomly turn black (not the entire screen just the lens window).  Makes it difficult to navigate with my vision issues.

Any solutions would be appreciated.  Thanks

I am by no means an expert on Windows 10, but I can let you know how I resolved the problem on my own PC. My PC has an nVidia graphics card which works just fine with all applications with the exception of Magnifier.

• Ensure nVidia Control Panel is installed and enter the control panel via a right click on the desktop screen, then select the nVidia Control Panel option in the context menu.
• On the left side of the application which is open, there is the option for manage 3D settings. Select this option. I know you probably aren't bothered by 3D anything - it's just where the settings are.
• On the right side of the screen select the 'Program Settings' tab.
• If the drop down selector in part 1 does not contain magnifier (and it probably won't,) click the 'Add' button and then the 'Browse' button.
• Navigate to c:\windows\system32\magnify.exe and double click on it. Doing this will add it to list.
• Choose c:\windows\system32\magnify.exe from the list.
• In part 2 choose integrated graphics from the drop down.
• Click the Apply button.
