I am unable to track a user

• I goto Your Sites
• Click the plus icon
• Toggle Track a user
• It shows "none selected", and i click the > arrow
• A search comes up. I've tried entering my display name, my login name, even the numeric ID for the user.
• Absolutely nothing happens when i click search

I only have the Stack Overflow checkmarked for the sites
