VB6 DLLs in Dellphi

I made a DLL in VB6 to use in a delphi project.  It seems that when I make a change to the DLL in VB and recompile, I must also re-import the type library in the Delphi project or it won't work.  Am I doing something wrong?  I thought the point of DLLs was so that you would only have to recompile the DLL if it was changed.  Is there a way around this?

you must re-import type lib in delphi only if interfaces are changed on DLL side
if interfaces are the same and only implementation has changed, all you need
is swap DLL files

fbk2000 is talking about COM DLLs (VB by default creates COMs) this has nothing to do with loading "classic" libraries
