Running two apps

HI
Im trying to run 2 apps from one button. But The second one always waits for the first one to be closed before it runs. I have tried different combinations but it always the same.any ideas?

Set DUAL=ON
Set FOCUS=left
go "..\usb data"
"..\ub data\USB macro.xlsx"
"..\usb data\WORD macro labels.txt" 
www.google.com
Set FOCUS=Right
go "..m\Images\Graduations"
Set VIEWPANE=ON

Which two apps are you referring to specifically? The .xlsx file and the .txt file?
