When searching for users to add to a course with the People Picker, the links to the user's profile should open in a new window, not navigate directly to their profile from the People Picker window.

I can't count the number of times I've been adding people to a course and accidentally clicked on a name instead of the checkbox next to their name.

This takes you to their user profile page and resets all the names that were added and you have to start all over again.
