Progress Bar Function Fails on Windows 8 only

[knightrid]

I have a simple function to display a progress meter and it works fine on XP Pro 32-bit, Win7 Enterprise 32-bit, and Win7 Enterprise 64-bit, but there is absolutely no output displayed on a Windows 8 system: 

 

Global $bSilent = False

Func _Lync2013_Progress($sTitle, $sMessage, $iLoopDelay) ; Make a progress bar to inform the user.
        Local $i
    If $bSilent = False Then
        ProgressOn($sTitle, $sMessage, "0 percent")
        For $i = 10 To 100 Step 10
            Sleep($iLoopDelay)
            ProgressSet($i, $i & " percent")
        Next
        ProgressSet(100, "Step completed", "Continuing Installation")
        Sleep(10000)
        ProgressOff()
    Else
        Sleep($timer_min * 3)
    EndIf
EndFunc   ;==>_Lync2013_Progress

_Lync2013_Progress("Searching for Lync 2010","Attempting system cleanup", 60000)

I've used this code successfully before, but never on Windows 8.

Have you tried it with the GUICtrlCreateProgress function instead? I'm wondering if it's something in the ProgressOn function that's not working or something to do with progress bars in general in Win8.

BTW, the function you're using doesn't make a lot of sense the way it's written unless you're just using the progress window to delay the script. Because that's all it's doing. If you just wanted to display a progress bar while you're script is doing something else, a progressbar using the marquee setting would be a better choice.

I have some forms that I abandoned because I was running low on time and didn't want to deal with the Resources UDF. I think I need to go ahead and implement the forms using the Resources UDF. 

I read several other posts to the forum about people who had problems with specific functions in Windows 8. I was basically using the progress bar as a delay until I had more time to come back and implement my original design. 

The environment I'm in is extremely diverse and I sometimes find functions don't work consistently across the variety of OS configurations that we have. I was going to submit this as a possible bug, but I wanted to bounce it off others to see if they had run into similar issues.
