Hello i have got a problem..

I have loop with the basic lines and plus one button.. If is button clicked, it start function and there's my problem.. When I have in my function Sleep command it freeze all buttons.. and GUI is useless then.. What's wrong? Which command can fix it? Is Sleep() correct with GUI?

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

$frm = GUICreate("Form1", 258, 65, 192, 132)
$startbtn = GUICtrlCreateButton("START", 16, 16, 75, 25)
$txt = GUICtrlCreateLabel("Program is waiting", 112, 20, 200, 20)
GUISetState(@SW_SHOW)



While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $startbtn
            $sbtn = GUICtrlRead($startbtn)
            If $sbtn = "START" Then
                GUICtrlSetData($startbtn, "STOP")
                GUICtrlSetData($txt, "Program in progress...")
                _Main()
            Else
                GUICtrlSetData($startbtn, "START")
                GUICtrlSetData($txt, "Program is waiting")
            EndIf
    EndSwitch
WEnd


Func _Main()
    Sleep(30000)
EndFunc   ;==>_Main

There is nothing "wrong" as your gui message loop is interrupted by the call to the _Main() FUNC.
So it is really an design issue. :)

One thing to look for is to use the event mode for the GUI which allows for a alternative design.
