If you're using the subscribe to comments script there's an important bug fix. Basically, it's been discovered that Safari browsers on Macs will crash when they attempt to submit a comment. The download has been updated. But if you have it already installed, it's a simple fix (see "more" text).
(FYI – If you're on Safari – this bug fix has been made to this site, so you should be able to comment here without crashing)
Please note that users on Safari (and I've noticed some other browsers as well) will have their comment submitted twice if they click their "back" button after submitting their comment. You will probably want to make a note somewhere on your form that users should refrain from hitting their back button. (Make sure you provide them with alternative links – ie. a link to the main home page of your site, or links to advance to the next post, etc.)
Here's the fix. In your files for this script will be one called "processing.tmpl". Open this in a text editor, and look for this:
<script language="javascript">
window.history.forward(1);
</script>
Copy the below and paste it in it's place:
<script language="javascript">
<!–
function Is() {
agent = navigator.userAgent.toLowerCase();
this.mac = (agent.indexOf("mac")!=-1);
this.safari = (this.mac && (agent.indexOf("safari")!=-1));
}
var is = new Is();
if (!is.safari) {
window.history.forward(1);
}
//–>
</script>
(This bug fix makes use of the browser sniffer I just posted about which is located here)
