I've recently implemented with success the IDocHostUIHandler
interface which permit to disable popup men� on right click,
or add your, or do other things....

Good enjoy

Using mode is:

...
..
.

// navigates to "about:blank" (necessary to obtain a non NULL Browser
IDispatch interface)
WideString Address = "about:blank";
Browser->Navigate(Address);
while(Browser->Busy)
    Application->ProcessMessages();

// recovers the Browser IDispatch interface
LPDISPATCH Dispatch = Browser->Document;

// sets new IDocHostUIHandler
FDocHostUIHandler = NULL;
ICustomDoc *CustomDoc = NULL;
Dispatch->QueryInterface(IID_ICustomDoc,(LPVOID *) &CustomDoc);
FDocHostUIHandler = new QDocHostUIHandler();
CustomDoc->SetUIHandler((IDocHostUIHandler * ) FDocHostUIHandler);
CustomDoc->Release();
Dispatch->Release();

// navigates to google home page
Address = "http://www.google.com";
Browser->Navigate(Address);
