TAdvStringGrid - html cell become BLACK on focus


I'm using TMS TAdvStringGrid version to build a table of 20 rows and 8 columns

I'm setting one of the cell in a html fashion
'<a href="Details" title="' + X.DetailsText + '">' +  '<FONT color="#' +  Color + '">' + 'Details' + '</FONT></a>';

When user press the anchor I'm switching the selected line to be the row of the clicked cell.

If the user presses in that cell again but not on the anchor itself then the cell turns BLACK

I guess it some sort of focus, but BLACK for text and BLACK for background....

What to do ?

Even a work around will be appreciated !
