[lazarus] bug in TStringGrid

[Rainer Hamann]

I try to develop a component for lazarus like TDataGrid from ec-software for 
Delphi. I need the possibility to define different editor types like TEdit, 
TComboBox, TCalendar and none (readonly) for each column auf TStringGrid from 
Jesus R. If I have defined a real editor (one of the three first ones) and 
click on a cell of that column, everything works fine, but clicking on a 
second cell with no editor defined and clicking on the first cell again, the 
OnSelection event of TStringGrid doesn't work anymore.
