Hi Gang!

Here is a weird problem I ran across in an older application that I need to fix.

In this POS app, there is a startup program call pos_strt.prg

This is a bit of the code in pos_strt...

_EXIT = .F.
DO WHILE _EXIT = .F.
	_EXIT = .T.
	DO Mainpops WITH _EXIT
*TMT 12/12/08
ENDDO

It's job is to create a system menu and wait until the user exits the menu, then loop back and create a brand new menu to use.... or to exit out.

Here is the code in Mainpops.prg

******************************************************
*******************************************************************
*  Description:  This program will create the POS menu that appears 
*                at the top of the screen, it will also cycle back
*                after every selection is completed.
*******************************************************************
PROCEDURE MAINPOPS
PARAMETER _EXITPOS

CLEAR

*main_menu = "Main_Menu"
SET SYSMENU TO 
*SET SYSMENU automatic

main_menu = "_mSysMenu"

*DEFINE MENU &Main_Menu BAR AT LINE 1
DEFINE MENU &Main_Menu

DEFINE PAD _Cash_Reg  OF &Main_Menu PROMPT "\<Cash Register"
DEFINE PAD _Inventory OF &Main_Menu PROMPT "\<Inventory"    
DEFINE PAD _Utilities OF &Main_Menu PROMPT "\<Utilities"    
DEFINE PAD _Exit      OF &Main_Menu PROMPT "E\<xit"         

ON SELECTION PAD _Cash_Reg  OF &Main_Menu DO Regtemp
ON PAD _Inventory OF &Main_Menu ACTIVATE POPUP Inventory
ON PAD _Utilities OF &Main_Menu ACTIVATE POPUP Utilities
ON SELECTION PAD _Exit      OF &Main_Menu RETURN

*******************************************************************
-SNIP-

ACTIVATE MENU &Main_Menu

_EXITPOS = .F.

RETURN

This is the Menu. If the user selects to exit, then a RETURN is done while _EXITPOS is still True, so the loop up above exits.

Ok.... so far so good.

If the app has the focus, then the CPU Usage is around 2 or 3 %.

However, when a user switches away from the App to another application, the CPU usage of the App goes through the Roof !! around 98% !!!. For some reason, the Mainpops is not being done properly, and is being exited, and the loop in Pos_strt is running like crazy!!!

Worse, if you minimize the App to the TaskBar, the same thing happens, but you CANNOT Maximize the app anymore!!!

Weird....

Any ideas????

Thanks!
