Only thing I have to remember is which version of software
module is using which version of library - and to shut down
Builder before trying to open 'the other type' <g>

I can even go back to a particular release of each version
of IBO, but I've a frozen build for each that I use
normally, and the latest version is on Builder6.

On Builder5 even if you go in with the wrong library set up,
and get messages flagging the mistake, then close without a
save does not give any problems. I'd assume Delphi would be
the same, but as long as you have backups ....
