Unable to see DataRelation graphic in DataSet designer

[Robert Brown]

Hi all,

I have a simple dataset with a relation between 2 tables. The problem
is that I cannot see the "relation object represented as a gray
square" as I should (and have done in the past). Is there anything
wrong with the relationship?
Thanks,

Rob
