You do long lasting blocking code in WM_COMMAND.

This is main source of odd behaviour.

Here is fixed version, blocking code moved from WM_COMMAND to main message loop.

But as you can see some problems remains.

I think it's because Graphic control is very nonstandard AutoIt's control so its usage is limited.

I recommend to use Picture control instead. You can use GDI or GDI+ API functions to paint whatever you want on that pictur control if needed.

EDIT: using label instead of graphic fixed it

Here is the link to useful info on WIKI

http://www.autoitscript.com/wiki/GUIRegisterMsg

[JScript]

And why not use that way?

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

Local $sgui = GUICreate('Testing........', 500, 400, 100, 100)
Local $sBtn[2] = [GUICtrlCreateButton('UP', 225, 20, 50, 30), GUICtrlCreateButton('DOWN', 225, 350, 50, 30)]
Local $sLabel = GUICtrlCreateGraphic(225, 70, 50, 35)
GUICtrlSetState(-1, $GUI_ONTOP)
GUICtrlSetBkColor(-1, 0x000000)
GUISetState()

Global $drag = True
Local $nMsg, $sPos

While $nMsg <> -3
    $nMsg = GUIGetMsg()

    Switch $nMsg
        Case $sBtn[0]
            $sPos = ControlGetPos($sgui, '', $sLabel)
            If $sPos[1] + $sPos[3] <= 70 + 25 Then ContinueLoop
            ControlMove($sgui, '', $sLabel, $sPos[0], $sPos[1] - 10)
        Case $sBtn[1]
            $sPos = ControlGetPos($sgui, '', $sLabel)
            If $sPos[1] + $sPos[3] >= 345 Then ContinueLoop
            ControlMove($sgui, '', $sLabel, $sPos[0], $sPos[1] + 10)
        Case $sLabel
            $sPos = ControlGetPos($sgui, '', $sLabel)
            While 1
                $sMousePos = GUIGetCursorInfo($sgui)
                If Not $sMousePos[2] Then ExitLoop
                If $sMousePos[1] <= 345 - 35 And $sMousePos[1] >= 70 - 10 Then
                    ControlMove($sgui, '', $sLabel, 225, $sMousePos[1])
                EndIf
            WEnd
    EndSwitch
WEnd
