The forums are buggy like hell in all browsers, for all users.
Specifically in this thread, we're talking about the dysfunctionality of the Link and HTML buttons. Do these currently work for you, Crusty? Please post a link to test this.
When I made the first reply to Casique, those things still worked for me in Chrome & Firefox, too. But, as I said, they used to work intermittently, and a browser restart was necessary sometimes to fix that.
Now, it appears that even multiple restarts of a browser don't accomplish anything. (And I'm writing from a machine with freshly re-installed Windows.)
Most of all, it's regrettable that the finest and fastest, and standards-based, browser of them all, Opera, stopped working in these forums on the day of the last product update, 13th of August. As has been mentioned, the bugs in these forums are on the increase, rather than on the decrease.
