I'm constantly having this issue in IE 11 with Adobe DC. It's bothersome to my users and frustrating to me because all I can do is reboot the machines. I've tried uninstalling and reinstalling Adobe and it works for a while but then it just repeats the problem again. Adobe is an add on and it is enabled and yet when my users try to open DC in IE they get nothing, or a gray screen. This works in Chrome however, because of other applications I can't install Chrome on my machines. Is there an solution to this annoying issue?
