Software Open Office Impress Hyperlink color.

[Zatnikitelman]

I'm working on an Impress (PowerPoint) Presentation for college and I need a document hyperlink to change colors once it's been clicked on or visited. I've already set the color of unvisited and visited hyperlinks in the Tools>Options menu, but when I click on a link on one slide, then come back to it, the link is the same color.
Anyone know what's wrong?
Thanks,
Matt

Hate to bump, but I need to add something:
The hyperlinks don't just have to change color, they can also disappear. So if I click let's say "100" on the first slide, then come back to that slide "100" is either not there any more, or hidden or something.
