I am trying to copy a new quiz from my sandbox to my rostered course for students.  When copying, it appears to copy correctly and is located in the module where I copied it to.  However, student's can't access it.  When I click on "build" I get a message that says "copying assignment" that never goes away.  I have tried renaming the quiz in my sandbox and trying again, and I get the same message.  Now I am experiencing the same thing with another quiz that I created in my sandbox just a few days ago.  Is there anything I can do to get my quizzes to copy?

Thanks,

DM
