[DUG] ClientDataset and Key Violation

[Rohit Gupta]

Found it,

It fails on an index being of type largeint.  If its changed to string 
which we dont want to do, then it works fine. 

The million dollar question is why does it fail only on two out several 
hundred workstations ?  Does anyone know what dlls in windows implement 
ole ?
