Well I dont have a long experiance in MySql but as I got since now MySql is so sensitive or has not the good performance as I felf in MS-SQL & Oracle!
Anyway the things u should check is:
1_ Primary & Forien key must be in DataType
2_ Check unsign tag in ur table
3_ Both tables must be in same Engine

HTH.
