$Obj = ObjCreate("Shell.Explorer.2")
$Obj2 = ObjCreate("Shell.Explorer.2")
$GX = GUICtrlCreateObj($Obj, 0, 0, 800, 250)
$GX2 = GUICtrlCreateObj($Obj2, 0, 350, 800, 250)
$Obj.Navigate("google.com")
$Obj2.Navigate("google.com")
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit
EndSwitch
WEnd
