IE document.parentWindow.pageYOffset fails for no apparent reason

Global $oIE = _IECreate("http://www.geom.uiuc.edu/~huberty/math5337/groupe/digits.html", 1, 1)
$oIE.document.parentWindow.scrollBy(0, 200)
ConsoleWrite("scrolled "& $oIE.document.body.scrollTop &@CRLF)
_IENavigate($oIE, "https://www.google.com/search?q=wikipedia&sourceid=ie7&rls=com.microsoft:en-US:IE-Address&ie=&oe=")
sleep(200)
$oIE.document.parentWindow.scrollBy(0, 200)
ConsoleWrite("scrolled "& $oIE.document.parentWindow.pageYOffset &@CRLF)
exit

What I am trying to do is find out how far down the page is scrolled. The .pageYOffset() ALWAYS fails for me and I cannot tell why. If I hit F12 (dev options) and enter "document.parentWindow.pageYOffset" In the console and run it, it ALWAYS works and gives me the correct value. I know the .parentWindow in my script above is correct because scrollBy() ALWAYS works, yet pageYOffset() doesn't

I also tried using document.body.scrollTop and it only seems to work for SOME pages, and not for others, but when it works it works both from autoit AND the IE dev console, and when it does not work it doesn't work on either. At least it's consistent.

Why does pageYOffset work in the dev console of IE but NOT from autoit? 
Why does scrollTop only work on SOME pages?

Windows 8.1 64 bit, running IE 11.0.23
Edit1: updated test.

I found a solution that seems to work (for now). I could have sworn I tried this ten minutes ago and it didn't work at all.. See edit

$oIE.document.body.scrollTop

Edit: Nope! Works for some pages, and NOT for others. See this test script:
 

Global $oIE = _IECreate("http://www.geom.uiuc.edu/~huberty/math5337/groupe/digits.html", 1, 1)
$oIE.document.parentWindow.scrollBy(0, 200)
ConsoleWrite("scrolled "&$oIE.document.body.scrollTop &@CRLF)
_IENavigate($oIE, "https://www.google.com/search?q=wikipedia&sourceid=ie7&rls=com.microsoft:en-US:IE-Address&ie=&oe=")
sleep(200)
$oIE.document.parentWindow.scrollBy(0, 200)
ConsoleWrite("scrolled "&$oIE.document.body.scrollTop &@CRLF)
exit

I want to get how scrolled ANY page is.

      This is a little experiment that makes use of a "Browser Control" embedded in a GUI in order to be able to use AutoIt, HTML, JavaScript and CSS all together.
      This little toy will only work on systems with IE11.
      The purpose is to drag all the names of the scientists & drop on the right ones. (among scientists it has also infiltrated an intruder). I hope you find it entertaining.
      I've posted it here in the hope to have some suggestions on how to improve it all (I mean the interaction between Autoit Javascript html and css). Thanks

      Hello all, 
      I've written a script that pulls info from some web pages, saves the results to variables, and prints it out to a Word document. I've tried to make this script work with a minimum of user interaction. I've noticed an issue happens when I run the script and I have another window set as active, like SciTE for example. It inserts an "ETX" character. I've done this with Notepad too. It displays an upside down L character. Any particular reason why? Unfortunately, I can't post any code. Basically, it gets a collection of tags, applies a test to find the values I want, then pulls the innerhtml from said tag. Then it assigns the results to a global variable.  Any help would be appreciated.

      Hi All,
      I've coded the small script below, but it can't seem to get the instance of Windows Media player as it keeps going to @error, I've not used com objects before so any assistance would be appreciate. I already have WMP open and minimised. I retrieved "WMPlayerApp" from the AutoIT info tool, I've included a copy below.
      I'm using these sources:
      https://msdn.microsoft.com/en-us/library/dd564085.aspx
      https://msdn.microsoft.com/en-us/library/dd564018.aspx
      $oWMP = ObjGet("", "WMPlayerApp") If @error Then MsgBox(0, "Can't get WMP", "Couldn't connect to the WMP instance") Exit EndIf $wmpPlayState = $oWMP.playState MsgBox(0, "Play State", $wmpPlayState) $wmpSongName = $oWMP.currentMedia.name MsgBox(0, "Play State", $wmpSongName) I've also seen references to the below, but I want to get an existing open WMP:
      ObjCreate("wmplayer.OCX") and have looked at the WMP.udf but can't see how it will do either of the functions I've coded above.
