I can't keep my paws off the code running my blog! I've been fiddling with it a bit more today.

I had previously changed some of the JavaScript used in the Comment form over to PHP, but then realised that some of the templates are not called via a PHP file but through CGI which makes it very hard to implement the same code. I found a tutorial that shows how you can do it, going back to using JavaScript... so I bit the bullet and have removed the PHP code again and added back the JS I previously removed.

Most people won't notice a difference, but now the comment form looks the same on the Individual Archive page, the Comment Preview page, the Comment Error Page and the popup Comment Listing Page (which should be disabled). Not exactly the solution I'd prefer, but it works and does look a lot better. Oh well.
