Okay, Sergey, it's already working real nice. Thank you very much!

The following is what I put in the Cleanup program which I called ResetEnv.prg:

* ResetEnv.prg
WAIT WINDOW NOWAIT "Cleaning up environment..."
CLEAR
CANCEL
CLEAR MEMORY
CLEAR ALL
SET RESOURCE ON
SET SYSMENU TO DEFAULT
SET HELP ON

I did the Admin Menu Definition exactly as you stated:

* Admin_menu.prg called in Config.fpw:
DEFINE PAD padAdmin OF _MSYSMENU PROMPT "Admin"
ON PAD padAdmin OF _MSYSMENU ACTIVATE POPUP popAdmin
DEFINE POPUP popAdmin MARGIN RELATIVE COLOR SCHEME 4
DEFINE BAR 1 OF popAdmin PROMPT '\<Reset Environment'
ON SELECTION BAR 1 OF popAdmin DO C:\DEV\ResetEnv.PRG

Here's the Config.fpw file's contents:

CLOCK=STATUS
CENTURY=ON
TITLE="Get Data Development in VFP 9.0"
RESOURCE="C:\DEV\GETDATA\FOXUSER.DBF"
RESOURCE=ON
HELP=ON
DEFAULT=C:\DEV\GETDATA
TMPFILES=c:\TEMP
