WebUIDelegateMBS Question

With WebUIDelegateMBS I can change the context menu of a html viewer. But can I do this only for specific locations?

I’m creating html that is a preview for emails with embedded attachments:


<img src="data:image/png;base64,

Over these links I need the change in the context menu. But not anywhere else.

Another question: is there an MBS function to change the mouse cursor over links in the html viewer. The Xojo one doesn’t do this.
