tDBAdvStringGrid bug(?) : Method hides ancestor

Hello TMS Team,

I still use tDBAdvStringGrid because tDBAdvGrid doesn't work for my purposes. 

When I compule my application, I get the warning "[DCC Warning] DBAdvGrd.pas(216): W1010 Method 'UpdateRowCount' hides virtual method of base type 'TAdvStringGrid'".

The "Override" keyword appears to be missing.   Is this by accident, or on purpose?
