Don't use a MsgBox.

MsgBox is a blocking function, meaning the script halts until the box is closed. Make your own MsgBox using a GUI instead of the built-in msgbox function.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

simple own msgbox:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <StaticConstants.au3>
$action = ""
Opt("GUIOnEventMode", 0)
  $gui_3 = GUICreate("msgbox", 326, 145, -1, -1, $WS_CAPTION)
  $gui_3text = GUICtrlCreateLabel("text", 10, 50, 306, 20, $SS_CENTER)
  $gui_3ja = GUICtrlCreateButton("Yes", 75, 90, 50, 20)
  $gui_3nein = GUICtrlCreateButton("No", 201, 90, 50, 20)
  GUISetState()
  while 1
   sleep(20)
   $mMsg = GUIGetMsg(1)
      Switch $mMsg[0]
    case $gui_3ja
     $action = "yes"
     exitloop
    case $gui_3nein
     $action = "no"
     exitloop
   EndSwitch
  wend
  msgbox(64, "info", "you clicked "&$action)

Or if you do not need the return value of the MsgBox you could use something like this:

Run(@AutoItExe & ' /AutoIt3ExecuteLine  "MsgBox(0, ''Hello World!'', ''Hi!'', 10)"')

For $i = 10 To 1 Step -1
    ToolTip($i)
    Sleep(1000)
Next

Programming today is a race between software engineers striving to
build bigger and better idiot-proof programs, and the Universe
trying to produce bigger and better idiots.
So far, the Universe is winning.

I've used CreateThread with MessageBoxIndirect successfully in the past. It doesn't seem to crash autoit like creating threads on internal callback pointers (for example).

Example:

Main()

Func Main()
    Local $hThread
    For $i = 1 To 5
        $hThread = _ErrorBox("Here I am: #" & $i)
        If $hThread Then DllCall("kernel32.dll", "bool", "CloseHandle", "handle", $hThread)
    Next

    GUICreate("Wait for it...")
    GUISetState()
    Do
    Until GUIGetMsg() = -3
EndFunc

Func _ErrorBox($szMessage)
    Local $tMSG = "uint cbSize;hwnd hwndOwner;ptr hInstance;ptr lpszText;ptr lpszCaption;dword dwStyle;ptr lpszIcon;dword dwContextHelpId;" & _
            "ptr lpfnMsgBoxCallback;dword dwLanguageId"
    Local $MSG = DllStructCreate($tMSG)
    DllStructSetData($MSG, "cbSize", DllStructGetSize($MSG))
    Local $pText = DllStructCreate("wchar[" & StringLen($szMessage) + 1 & "]")
    DllStructSetData($pText, 1, $szMessage & ChrW(0)) ; terminating null
    DllStructSetData($MSG, "lpszText", DllStructGetPtr($pText))
    DllStructSetData($MSG, "lpszCaption", 0)
    DllStructSetData($MSG, "dwStyle", 16) ; MB_OK|MB_ICONERROR

    Local $hMod = DllCall("kernel32.dll", "handle", "GetModuleHandleW", "wstr", "user32.dll")
    Local $pMBIW = DllCall("kernel32.dll", "ptr", "GetProcAddress", "handle", $hMod[0], "str", "MessageBoxIndirectW")
    Local $hThread = DllCall("kernel32.dll", "handle", "CreateThread", "ptr", 0, "dword", 0, "ptr", $pMBIW[0], "ptr", DllStructGetPtr($MSG), "dword", 0, "ptr", 0)
    If $hThread[0] Then WinWait("Error", $szMessage, 5) ; wait for message box to be displayed
    Return $hThread[0]
EndFunc   ;==>_ErrorBox
