I work in IT Field Services and IE is the browser version that is in Windows 7. When Windows 10 came out the updated microsoft browser is now Edge. I do not feel it works that well as there really is no way to use google search engine. You have to use Bing. I have dumped Microsoft IE and Edge and now modtly use Chrome and FireFox. Hope that helps explain the differences.
I am using LR5.7 and have the same issues with Win 10. Very frustrating. I have tried all the fixes I could find online and nothing seems to work. Everyone says to turn GPU off but in 5.7 there is no option to do that in Edit/Preferrences/performance
That was truely tear inducing. My wife and I belong to the Hearing Loss Association of America (HLAA) and see this all the time and I never get tired of it. The pure JOY.
