Looking for advices about a bug when using the slider on Safari

[damdam]

Hi all

I'm using this slider for a friend portfolio. ( http://www.cloosedesign.com/new/portfolio.php?realisation=72 )

I'm facing a little bug when using it on Safari.

On the "portfolio" page on the left you can see the name of the works. And when clicking on it, it shows the slider with the corresponding images

On Safari, when I click on a work sometimes the text of the Footer disappear and then re appear (it is very fast but tiring). Sometimes this bug appear after the 2nd or the 3rd click, and sometimes the bug appear after more clicks.

I don't have this bug on other browsers.

Anyone have an idea where and how I can fix this ? 

Thanks in advance for your help.
