Hi. I have this piece of code

Rect mw;

public void Start()
{
    mw = new Rect(10, 10, 300, 300);
}

void func(int id)
{
    GUILayout.Button(new GUIContent("A", "B"));
}

public void OnGUI()
{
    mw = GUILayout.Window(10, mw, func, "aaa");
    GUI.Label(new Rect(20, 100, 50, 50), GUI.tooltip);
}

this should display a tooltip when the cursor hovers on the button. now, this code does not work. the tooltip is not displayed. it works if i move the GUI.Label instruction inside func function, but this forces me to display the tooltip inside the window and it is not a feasible solution. it seems GUI.tooltip is not updated if the update occurs inside the window. any ideas?
