Image: Windows Seven Forums.
I think I have fixed the black sections problem on my screenshots. I may be in Windows 10 but the above Windows 7 site has helped to solve two problems for me. If I use Shift PrtScr I get an image of both my monitors which is sometimes handy but usually I just want one screen. Now I know I can use Alt PrtScr and just get the active desktop I am using. I didn’t know that. The forum site gives some good information about screenshots. I usually save mine straight to the desktop because it is easy to find them there.Taking one screen at a time means I am not getting the black sections on each of the screens in the screen shot, so now I have narrowed that down to being a dual screen issue with Windows 10.
