	When I start a new Lane type diagram, I call the following code. The trouble is I get a IndexOutOfRangeException when I call grid.RowHeaders.Clear(); Is this a bug in the DLL or am I not using it correctly? DavidL private void InitialiseLanes() { flowChart.ClearAll(); flowChart.UndoManager.UndoEnabled = false; // Initialize grid Grid grid = flowChart.LaneGrid; grid.RowHeaders.Clear(); grid.ColumnHeaders.Clear(); ........

	Try setting grid.RowCount and grid.ColunmCount to 0, instead of calling Headers.Clear(). Stoyan

	This is definitely something that should not happen. Unfortunately I am unable to reproduce it here. Is it possible to send me the stack trace of the exception and/or the initialization code you are using before invoking this method? Thank you, Meppy

	The exception does not happen the first time I call this code, but the second time. i.e. when there are actually rows and columns that I want to clear out in order to start a new chart. David

	BTW, Stoyan's solution gives the same exception. David.

	Any chance you can send me your initialization code (particularly the code which initializes the lane header collections before they are cleared)? The exception's stack trace can also be useful. Thank you, Meppy
