I've searched the forums but I can't find the solution to this problem.  I have a student who has met the module's prerequisite (a discussion board which I did grade for him) but the next module is still locked.  Other students are able to proceed.  I had him check this in different browsers thinking it might be a cookie/cache issue on his end.  Any suggestions?
