WordPress 2.6 Crashes Safari
Soon after I upgraded to Wordpress 2.6, I discovered that the Wordpress' dashboard and post/page editor cause the Safari 1.3 browser to crash. Though other Wordpress 2.6 admin functions continue to work fine in Safari 1.3, including the widget functions, without the Dashboard, users can't login, and without the post/page editor, users can't update their blog. This makes Wordpress 2.6 completely unusable in Safari 1.3.
A quick search of the forums showed that this problem has cropped up for other Wordpress users and that it may extend to Safari 2 as well. Here what one user had to say on wordpress.com forums.
