NT4.0 and Data corruption

Hi all, I have a delphi database application which is running in several
OSes.  The Application is written with delphi 1.02 and the BDE is 2.52.
The Application runs fine for most part in Win95 and Win3.1, also it seems
fine in Lantastic and Novell.  But I am Experiencing alot of database
corruption and index out of date on the few customers who have the system
in NT 4.0.  

Is Anybody else have the same problem?

What is The problem?  I read that Service Pack2 solves some data corruption
in databases, Is that the problem?

Thanks in advance.
