Docking Manager & Docking window with iteself

I am encountering a problem with the DockingManager in Syncfusion 4.1.0.62 (was also in 4.1.0.50 as well) and VS 2005. I have attached a sample project that should illustrate the problem, and these are the steps: Drag two of the panels (call them Panel A and Panel B) outside of the application (so they are both floating separately outside of the main window area). Now drag Panel A overtop of Panel B but don’t let go – so the docking guide appeaers. Now move it back to its last spot outside the main window. (As in, user starts to move Panel A, and then changes their mind and moves it back). Now if you click and drag Panel B (the one you almost docked Panel A with) – you will notice docking guide controls overtop of it, from the last operation. Enabling you to dock the window with itself - suffice to say, that doesn’t end well. The application will crash with an object reference not set to an instance of an object. If you can''t reproduce the problem, let me know and I can try to clarify the steps. Thanks! Jonathan
