[DUG] Com problem

[Robert Martin]

Yes, multiple copies.  Will retry cutting down to one and re registering 
it.  Good suggestion :)

I discovered I needed to add the .rdil file to the project.  Having done that all seemed ok.  I added the method in the typeLibrary screen then implemented the code.

It is almost like, even though I have defined the v call it hasn't actually been 'build' into the app.  I have checked the The rdil and tlb files and the new method looks the same as the existing methods.
