GGC ArgumentOutOfRangeException

Hi,
I am using a GGC with the dragcolumns set to true. There are no issues when I drag a column header and drop it on another column header.

But when I try dropping it anywhere else(ex in the table) it gives the following exception. I know that the drag drop will work only by placing the dragged column header on a different column header, but this exception is slowing down the app when the user tries this invalid operation. I want to suppress this exception from being thrown.

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
