IndexOutOfRangeException in DataBound grid

[Bijeshnath Ravindranath]

Hi
We are using version 4.4 of Syncfusion. We have a screen with a DataBoundGrid. Occasionally we are getting these exceptions while the user is editing:
2010-07-12 16:11:20,011 ERROR [4360] (ExceptionManager:0) - Index 4 is either negative or above rows count.
System.IndexOutOfRangeException: Index 4 is either negative or above rows count.

at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

We are not able to find out the cause as it does not seem to be happening inside our code. Can you tell me if this is any known issue? This works fine almost all of the time (and has been in place for a long time). But occasionally some users are getting this error and hence we would like to know if this is a known issue and if there is any fix/workaround etc.
thanks and regards
