DiagramView.OnMouseDown crashes in Vista

We have an application with a DiagramView and it works perfectly on xp clients but on Vista clients the following exception is thrown as soon as you click in the diagram.


System.AccessViolationException: Attempt to read or write protected memory. This is often an indication that other memory is corrupt.

at MindFusion.Diagramming.WinForms.DiagramView.EndEdit(Boolean accept)
at MindFusion.Diagramming.WinForms.DiagramView.OnMouseDown(MouseEventArgs e)
at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button, Int32 clicks)
at System.Windows.Forms.Control.WndProc(Message& m)
at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Does it happen after an inplace edit operation?

No, it happens right from the start.

We are running version 5.1.1.21015 of the Diagramming.WinForms dll, but I tried downgrading to version 5.1.1.19447 and then the problem disappeared.

5.1.1.21015 is what we sent you for the KeepRatio update? Could you check if the same happens with the 21375 build we sent you for the SnapToNodeBorder extension:
