In one of my sidebars, I have activated the generic WP Recent Posts widget.
I've noticed that when on any CoursePress-powered page, the content of that widget changes to be a CoursePress item.
This is usually whatever page you're on. For example if on the courses-dashboard page, it says Dashboard - Courses, and so on.
I'd guess it's most likely due to the fact that we use custom post types for much of coursepress functionality.
Any workarounds, fixes? Alternatively as a quick hack fix, I do have widget logic installed and right now it's just checking for is_page()...So maybe an additional conditional statement here for now?
