safari provlem - 1 button works, the other doesn't

[Dopple]

Hi there. I have 2 pay pal buttons on a site I am coding. www.ufreak.net
At the bottom right of the page in the box office part the 2 form buttons link to 2 different paypal payments.
I thought it may be the z-index: of the image so I gave it z:index 2. This hasn't helped. Can anyone shed light on why 1 would work but another wouldn't?
The css for the site is at www.ufreak.net/includes/ufreak.css.
Thanks in advance for any help which you can give.

Hmm. Even with Firefox it's not selectable. Very strange indeed.

Both buttons seem to work fine in FF for me. ??

Sorry I should have closed this down. I managed to sort it by shifting the z-index of the 2 images. (the button and the beveled edge image behind.) I wouldn't have thought this would affect it but there you go.
