Test to see if PowerPoint is loaded

[Grantgimp]

Can anyone come up with a more reliable way of testing if PowerPoint has fully loaded in 'Slide Show' mode that is just as easy? As you can see my method relies on first screen not having black pixels in certain places that'll work for me 99% of the time. I know that there are other solutions on the forum, but these seem more complicated than mine.

#include "ProcessListProperties.au3"
#include <array.au3>
#include <GUIConstantsEx.au3>
#include <GUIComboBox.au3>
$Directory=@DesktopDir & "\Current Service"
$ApplSrce=@ProgramFilesDir & "\Microsoft Office\OFFICE11\POWERPNT.EXE /s """
Run($ApplSrce & $Directory & "\words-150608.ppt")
WinWait("PowerPoint")
While 1
If PixelGetColor(0, 100) <> 0 and PixelGetColor(0, 200) <> 0 and PixelGetColor(0, 300) <> 0 and PixelGetColor(0, 400) <> 0 and PixelGetColor(0, 500) <> 0 Then
MsgBox(0,"", "opened")
ExitLoop
Else 
ContinueLoop
EndIf
WEnd

You can use the AutoIt Window Info Tool (AU3Info) to see pretty much everything that AutoIt will be able to see.
