COM jumble

Dear All,
Assume the following scenarion. There are 2 components A and B. Component A calls component B. I have added a new method to component B and compiled it. However I am not invoking the new method from component A. In such a case is it necessary to recompile component A.
Thanks in advance

As far as I know NO.

Dear Asabi,
In my case it gives me an automation error whenever i use component B without recompiling component A. Are there any settings in Visual Basic in this regard.
