Windows Vista: Weird WinSetOnTop() behavior.

[AngelicCare]

Code to start program (this part works):

Global $GlobalMatchMode
$GlobalMatchMode = 3
...
$CurrentWindow = WinGetHandle("[ACTIVE]","")
Run("c:\exe\desktopzoom.exe","c:\exe");EnvGet("WINDIR") & "\system32"
$ZoomWindowMoved = 0
Sleep(2000)
WinActivate($CurrentWindow)

And the following code associated with hotkey does not work:

Opt("WinTitleMatchMode",4)
$CurrentWindow = WinGetHandle("[ACTIVE]","")
Opt("WinTitleMatchMode",$GlobalMatchMode)
WinSetOnTop("Zoom", "", 1)
WinActivate($CurrentWindow)
Sleep(2000)

Window remains "not on top"...

Unless...

Unless...

You put a

MsgBox(4096,"","Zoom",1)

in front of this code.

Or active another "On top" window that already was "on top" and then deactivate it (used Autohotkey "Window Spy" for example).

Then "Zoom" window stays on top.

The idea is: It sets "On top" but window does not stays on top until "Zoom" window is active and other "On top" window gets activated: it can be "Task manager", "Alt-Tab" menu, or anything else that has "On top" status. If "Zoom" is not active when switching to other "On top" program - "Zoom" does not stay on top.

Working work-around:

WinSetOnTop("Zoom", "", 1)

;Workaround for Vista "on top" bug:
$CurrentWindow = WinGetHandle("[ACTIVE]","")
WinActivate("Zoom","")     ; Desired window to set "on top"
SplashTextOn ("Zoom mode","Zoom mode", 100,50,-1,-1,16)
WinActivate("Zoom mode")
Sleep(1000)
SplashOff ( )
WinActivate($CurrentWindow)
