Safari is giving problems (scale + not working)

[Pictor13]

Roundabout is a wonderfull piece of code, really nice and easy to use.

And that's extremly cross-browser.

But...
I'm having problem with Safari.

1. On Computer (latest version released for Windows)
   My LIs contain a different image each (different width) and on Safari they show of different sizes (less the width more the size).
   Maybe I set something wrong? (I'm not using EMs cause of the different dimensions)

2. On iPhone that's not showing;it stay as a common list of elements.

Are you able to give some advices on those problems?

Thank you,
and thanks anyway for the really well done script :)
