Green Park 2 with Safari: no links!

Hi! I am using the Green Park 2, enjoying it, but having a weird problem: with Safari I cannot click on any link placed in the sidebar!

This happens when in a page, there is almost no content. If, for example, a page contains only “hello world!”, then up to some space in the page, the links in the sidebar are not clickable. If I copy and paste a lot of text, then magically all the links are active.

What can I do? I mean, what can I do, except putting some dummy text ??

I am using WordPress 2.9.1 with the following plugins:
Avatars
NextGEN Gallery
OpenID
StatPress
WP-Mail-SMTP
WP-Polls
XRDS-Simple
