Can't login to musescore.org under Windows 10 with IE
I run Windows 10 on several machines at home, all upgraded from Windows 7, and can access and log into musescore.org under IE11 without issues. However, my two work PC's that were reimaged cleanly with Windows 10 can't log into MS under IE. I've tried Compatibility mode and several security options, but no go. Firefox works fine, but I don't consider that a solution.
Here's the chain of events I see:
1. I go to musescore.org. I need to login, so I click the login option.
2. I get brought to https://musescore.com/user/login?destination=frontpage with the login prompt. (Note the 'destination=frontpage')
3. I log in with my credentials and am brought to https://musescore.com/frontpage with a 'Page not found' error. I am logged into musescore.com (not where I wanted to be) but not musescore.org
When I login using FireFox, the page on point #2 is https://musescore.com/user?destination=cas/login which works. Using this link does't work under IE
Any ideas on how to correct this?
