Hi Peter, > I need to modify code that runs well in Delphi 3, but that fails in Delphi 5 > (due to changed behaviour in some VCL components).

When Delphi 1 shipped, it was numbered version 8, because it was the 8th edition of the (Pascal) compiler. Delphi 2 was version 9 and C++Builder was number version 9.3 (i.e. only a .3 version increase). Later, Borland regretted that decision, and C++Builder 3 resulted in a full increase of compiler version number. Only to change it's mind again with C++Builder 4, which is only good for half a version number upgrade. And as of version 5 of Delphi and C++Builder they both even share the same compiler version 13.
