Dear Sir

I have some problem during ArrowCreated Event.
When this event fire try to execute below the code
FC.Arrows.Remove(e.Arrow)

FC doesn't remove the arrow in the UI and still allow me to select the arrow. If after select the arrow and press delete button. FC raise a error

An unhandled exception of type 'System.ArgumentException' occurred in mscorlib.dll

Additional information: Cannot remove the specified item because it was not found in the specified Collection.

Please reply me asap

Thank you
