Hi,

This problem occurs regardless of of the syntax requested. 
Also I should further clarify that the problem only crops up when trying to 
retrieve records from windows(NT, 2000)-based implementations of Isite - it's 
fine with Linux and Unix implementations. Very odd and very frustrating! Has 
anybody else come across this problem?

Quoting Archie Warnock <warnock at awcubed.com>:
