The unlucky browser (designed with security in mind) has another problem.
It is vulnerable to phishers because Apple is doing nothing to protect their costumers. Their high security development cycle not only ignores (Apple isn't the only) the basic standards of security but also doesn't give to their users tools to effectively protect themselves.
I hope you didn't installed the crappy Windows version of Safari. If you did that first uninstall it, then use IE7 or Opera.
If you are a Mac User you have to switch, it's the only way out. At least to a more secure browser, Opera should be a good idea. Of course using bootcamp to install a copy of Windows Vista is a better choice (And in the next days would also be cheap).
Elsewhere don't cry if someone phish your secrets, I'm telling you what to do to avoid that.
