Just yesterday I upgraded to Win10 from Win7 Ultimate and quickly noticed that I was unable to type in the Edge browser. After searching all day for a solution online I finally figured out what appeared to be causing the problem......it was the KeyScrambler program I use. It worked fine with Win7 but now causes problems with Edge in Win10. I just installed the latest version of KeyScrambler which is supposed to be compatible but it worked once with a typed URL entry then quit. I am still investigating. Just had to use Task Manager to "unfreeze" the Edge browser. Anyone have any experience with this or a solution?
