Does anyone know how to get around the problem of Internet
Explorer 7 opening a new window when a user clicks on a mailto:
hyperlink that is within an online/published presentation?
I think it is a API problem within PowerPoint.
I get the same issue. A way round it would be to use the
Presenter feature with their email address set. You could show the
presenter, their photo and email address on a particular slide,
perhaps with some instructions. Not ideal and it doesn mean you
need to display the navigation pane.
