I have an UltraGrid with the BorderColor property set to Silver.
For the HotTrackRowCellAppearance I set the BorderColor to Black.

At runtime when moving my mouse over the rows the hot track only partially works. The top and left/right borders appear Black but the bottom border stays Silver.

When I change RowSpacingAfter property to greater then zero the hot track works correctly with all borders for the tracked row being Black. This leads me to believe the problem is that the rows overlap with the row below the one being hot tracked overlapping the hot tracked row and therefore hiding the Black border.

Assuming I am correct is there any way around this other than changing RowSpacingAfter? 

Thanks
