Hi Paul,

> be able to intercept a double click in the active-x control and then perform my own action rather than having it perform the default explorer action (navigate to a folder or open a file).

Technically, this is possible. All you need to do is to use BINDEVENTS() to hook into every single window that is hosted inside the browser and watch for the corresponding window message. Additionally, you need to watch out for the creation of new windows. However, this is not very easy to do in a way that works across various Windows versions. If there are alternatives like creating your own control I would check them out first.
