Dataset Abort with TTIWDBAdvWebGrid - Crashing App

Delphi 2009/IW 10.0.23/TMS Intraweb 4.1.1/Application Mode

Have a form with an IWDBNavigator and a TTIWDBAdvWebGrid, both hooked in to the same datasource.  If I perform an Abort procedure on the dataset in the OnBeforePost event, the entire application crashes with an Unhandled Exception (Operation Aborted).  This only seems to happen if I am using the TTIWDBAdvWebGrid.  Issuing an Abort while using other DB-aware components appears to be fine.
In addition, selecting Insert, then Cancel, from the IWDBNavigator does not cause any issues.  The grid appears to behave as expected.
Any thoughts or suggestions here?
