Do you have the following in your LaunchApp code

	#If .F.
	lResult = CrPr(	0, ;
					cCommandLine, ;
					0, 0, 0, 0, 0, ;
					uFromDir, ;
					@cStartUpInfo, ;
					@cProcessInfo)
	#Else
	lcApplicationName = ALLTRIM( This.icLaunchDir ) + ALLTRIM(    
                 This.icCommandLine ) + CHR( 0 )
	lResult = CrPr(	lcApplicationName, ;
					0, ;
					0, 0, 0, 0, 0, ;
					0, ;
					@cStartUpInfo, ;
					@cProcessInfo)
	#EndIf

I hate to say it but I may have been the culprit.
