Exception rearranging tabbed docking windows

Hi, we a customer has just caught an unhandled exception when attempting to drag-arrange tabbed docking panels. Unfortunately the only information I have is the following stack trace: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.Collections.ArrayList.get_Item(Int32 index) at Syncfusion.Windows.Forms.Tools.TabPageAdvCollection.get_Item(Int32 index) at Syncfusion.Windows.Forms.Tools.DockHost.ProvideTabFeedback(IDraggable idg, MouseAction action) at Syncfusion.Windows.Forms.Tools.DragFBProvider.ProcessMouseMove(IDraggable ctrl, Point ptscreen) at Syncfusion.Windows.Forms.Tools.DockHostController.HandleMouseMoveImp(MouseButtons button, Point pt) at Syncfusion.Windows.Forms.Tools.DockHost.OnMouseMove(MouseEventArgs e) at System.Windows.Forms.Control.WmMouseMove(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at Syncfusion.Windows.Forms.Tools.DockHost.WndProc(Message& msg) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Regards Kai Iske

Hi Kai, I tried to reproduce the problem, but was unable to. Some information regarding the setup of your application or a similar sample might help me track the problem down. Regards, Gregory Austin Syncfusion, Inc.

Gregory, I will try obtaining further information from the user as to how the docking panels were layed out before the exception was thrown. If I do find anything, I will open a Direct-Trac incident Thanks Regards Kai
