I am trying to responds to feedback posts, like this one. The site prompts me to sign in. I choose to use my TechSmith account on the Sign In pop up page. In Netscape, that's as far as it will go; I get a neverending "Signing in..." animation. So I switch to Edge, sign in, and try it again. The site shows I'm signed in, and the page shows my profile name and gives me the option to sign out. I try to post to the thread and I get a red bar with "Sorry! It looks like we were unable to sign you in. To complete your action, please sign in first."
