the "usual suspects": ;-)
- check the search path. are there older IB* files in there?
- ever worked with runtime packages? check %windows%\System or Sytem32
- check the Projects/BPL folder. clear out old stuff.
- in case you're compiling to a different directory, make sure there are
no old dcu's, dpc's or bpl's there.
- to be really safe, rename the old IBO directory and create a new one
(with the old name so you don't have to change your project's search path)
for the 4.2 stuff.
- open and rebuild all the packages from the "new old" dir.
- as a last check, search the Delphi dir for IB*.BPL's and look at the
timestamps, they should all be "fresh" now.
after this "brute force cleanup" all should work again...
