I just created this brand new database (MySQL 5.6 on Windows) and created a new admin user but now I can't modify any of the users privileges. I can click the Add Account button (notice there's one called "newuser") but then I can't set any of the privileges for this new user as everything is disabled, and no matter what user I select, everything is disabled. I can't even click on the other tabs.
Notice also that even though I have the "admin" user selected there is no Login Name displayed on the Login tab. It's all blank, like I haven't selected any user at all.
I've tried restarting the MySQL service, but that didn't help. What is going on here?
