I'm using invisible hyperlinks, i.e. I insert them by clicking
Slide show > Action Buttons > [icon in the upper left corner]
(like an invisible hyperlinked image)

When I copy-paste the hyperlinks, they don't work anymore: If you hover or click in their middle, nothing happens (except that if you click, you advance through the presentation); but if you hover/click along their outer edges, they work as they should. This is only true for the copy-pasted links, not for the original.

What's going on, and even more importantly--how do I correct for it? As I'm using a lot of identical hyperlinks, it's a pain to set them up from scratch each time, and copy-pasting would save me a **lot** of work.
