I can tell you it works here fine too, though I have a CVS version 
from about two weeks ago and I have BPL as a static library. And my 
wrappers are so big they break MSVC if you include any debug info at 
all!

Try enabling kernel loader snaps - these will tell you where it's 
faulting. Find an article on MSDN by Matt Pietrek - ignore all that 
modern crap in MSDN, it's a 1996 or thereabouts article which 
typically MS have expunged from the latest MSDN's with MSVC7.1 :(

Cheers,
Niall
