Preventing a window from closing (1 Viewer)

[petemod]

Hi,

I am trying to prevent my plugin from closing or in other words the user navigating away from the window.
From what I understand, when a user switches to a new screen the OnPageDestroy method gets called. Therefore I thought the following code would work (id 7856 is my plugin/window)

protected override void OnPageDestroy(int newWindowId)
    {
    	if(locked == true && newWindowId != 7856)
    		GUIWindowManager.ActivateWindow(7856);
    }

Now given locked is true, and the user presses 'h' (to go to home) the plugin should instead activate window 7856, however this is not happening?

Thanks in advance

Peter
