Delphi 3.0 and OLE

Has anyone had problems with upward compatability between Delphi 2 and 3?
 I am running into all kinds of problems with libraries not being found.
And if I comment out a library to try and get it to compile, the compiler
pastes it back on to the end of the uses statement.  Any help would be
appreciated.  Please respond by email.
