DllCallBack crash, if i don't move the GUI

[eukalyptus]

Hello

my script stops after a few callback´s BUT: if i move the GUI (clicking in the titlebar and moving around) the callback is running well till i release the mousebutton...

$RecordCallBack=DllCallbackRegister ("_RecordCallBack", "int", "hwnd;ptr;int;int")

$BASS = DllOpen(@ScriptDir & "\bass.dll")
Global $HRecord,$cbcount=0

GUICreate("TestCallBack")
GUISetState()


DllCall($BASS, "dword", "BASS_RecordInit", "dword", 0)
DllCall($BASS, "dword", "BASS_RecordSetDevice", "dword", 0)
$HRecord = DllCall($BASS, "hwnd", "BASS_RecordStart", "dword", 44100, "dword", 2, "dword", 128, "ptr", DllCallbackGetPtr($RecordCallBack), "dword", 0)


While 1
    sleep(50)
WEnd



Func _RecordCallBack($hwnd,$ptr,$int1,$int2)
    Local $Ret
    $cbcount+=1
    ToolTip($cbcount & " " & $ptr & " " & $int1)
    Return 1
EndFunc
