I am getting an AV on address 000000000 when calling GetInterface()
function.

Does anyone know if Delphi 3 actually had interfaces working? The exact same
code works with Delphi 5 and up. Haven't checked Delphi 4 yet. I presume it
works because the code has been there this was a while now without it
breaking for anyone.

I've got someone in a tight spot and I need this resolved ASAP. Any help
would be appreciated.
At this point I am just about to IFDEF out the interfaces for IB_Grid in
Delphi 3.

PS. I will soon be dropping Delphi 3 anyway.

Thanks,
