[DUG] Returning IDispatch instead of OleVariant in TypeLibrary

[Phil Middlemiss]

Yes, that's done the trick - thanks. I missed it the first time you 
mentioned it cause I was so caught up in trying to just get the thing 
reloading without errors.

I can now set the return value of a method to one of my dispInterfaces. 
Is this a good idea or should I just return an IDispInterface (concerned 
about cross language compatibility)?

Cheers,
Phil.
