I'm referencing some third-party COM dlls through IDE Add Reference in
VS .NET 2003. For all generated interop assemblies intellisence
autocomplete works OK, except for one. For the offending one I can
declare types and instantiate objects wo problems but I can't get
intellisence autocomplete to work. I tried it in C# and MC++
environment, no success. It works OK in Visual Basic .NET 2003?!  

Is this known IDE bug? Is there something else that I'm doing wrong?
