Using COM Created with Borland C++ Builder 6 with .NET

We are using .NET (C#) and we added several COM dlls as Resources to our
projects. These COM dll's were created using Borland C++ Builder 6. When we
add any COMs built with Borland into our .NET projects, we have functionality
problems with the Borland COM (icons disappearing). We wrote a little test
..NET application and added just one Borland COM dll and we still see the
problem (no icons). Has anyone had this problem? Any help would be greatly
appreciated.

Thanks,
Alex
