Dear all,

 

I have another problem with Access 2003 as front end with Postgre 8.1, ODBC version 8.02.02 Unicode.

 

I just upgrade the Point of Sales Program to Access 2003 MDE, all station running XP Home wth Access 2003 on P4 3.0, 512MB Memory, 40GB HDD. Server run Windows Server 2003 on P4 3.0, 1GB Memory, 72GB UWSCSI HDD.

 

Sometimes In POS Application, while user input sales transaction, this error message window appear :

 

"The information you were working might be lost. microsoft office Access can by you compact and repair."

 

with option to send or don't send this error report to Microsoft.
