I have a problem about Service crate with Delphi 7 as TSeviceApplication

I have create a Service that open a DBF with BDE.

My FILE1.DBF have a MDX file associated with some index.

FILE1.DBF have two fileds :

FIELDA String 10
FIELDB String 10

FILE1.MDX have 3 Index

1) FIELDA is FIELDA
2) FIELDB is FIELDA
3) FIELDSAB is Expression Index FIELDA+FIELDB

I open the DBF file with TTtable and not have problem when a user is logon, when I logoff user,
the services crash.
The problem is caused to Expression Index because when I changed the index structure and erase the index FIELDSAB
the service no have problem it's all OK.

Why ??
