Hello George,
I think I would like to enhance with " Single Instance ".
>>The Single Instance (MUTEX Class from November '98 FoxPro Advisor) process

Keep it simple, starting from the beginning,
What's the first step(s) in preparing an application for being recognized as already active.
Will I be required to load any special programs?
WorkStations are : Win95, Win98, and WinNT.
Network Application contains 7 tables + 2 Linked Tables largest 31K records.

Application Hiearchy follows:
Main.PRG calls MAIN FORM SET
MAIN FORM SET can call 7 other ENTRY Forms or Ten Reports or Report Builder
Closing any report or ENTRY Form returns the user to the MAIN FORM SET
Exiting the MAIN FORM SET returns to Main.PRG and runs Clean-UP code and Quits!

HISTORY:
The code @ 'Creating the MUTEX class' was originally placed in my Main.PRG but Did Not seem to work ---
I then tried to create a Form Class named MUTEX, to contain the code in the init
--- still nada
ran out of time.
I'm back, Let's find a place for the PROCEDURE Init code.
