activex

I'm developing an ActiveX EXE that exposes an specific class to a third-party software. This third-party software instanciates an object of this class and uses its methods.

Strangely, this third-party software destroys its object of my exposed class as soon as it calls an specific method, but I have no idea why this happens.

The only clue I have is that this method is the only one that returns a value. All the other ones are simple 'subs' that do not return any value, and when they are called nothing wrong happens.

I'm using VB6.

Do you guys have any idea of why it's happening?
