Lesson Builder - Missing Warning
While testing Lesson Builder in rc03 on  I found a problem with the instructor view for adding assignments using IE9 & FF16.
If an instructor attempts to add an assignment to a lesson builder page when the Assignments tool does not exist in the site, the following warning is supposed to be displayed:
There is no assignment tool available in the site.
However, on  there is no warning displayed for Assignments.
