[Lazarus] Strange dependency of units

[Alberto Narduzzi]

Just forgot one simple thing:

If you code compiled and worked good under Delphi, that is because 
Delphi is platform specific (that is, Windows specific) hence the unit 
GRIDS already had its implementation completely done; and unit GRIDS in 
Delphi may not be made of abstract classes at all.

You just hit the wrong unit at the wrong time; but at least now things 
may begin to get easier.


Again, cheers,
