Can't resolve external reference on Excel 2000
 

Hi,

I have an add-in that references an external ActiveX component. I've made a
change to the activeX DLL; the interfaces and method signatures have not
changed (GUID's and ID's are the same). After replacing the new ActiveX
component (I did not update reference for the add-in), I get a "compile
error" when the add-in loads. Opening the add-in and and checking the
references did not resolve the problem. I've also tried unregistering the old
DLL, registering the new DLL -- still fails. Oddly enough, this only happens
on Excel 2000. I don't get the error on Excel 97/2002/2003. Any ideas?

Thanks
