Forums mIRC Help IRC URL link - no connect

Thanks Poppy for those responses, I was refering to your previous post as one of the examples of others that have alluded to this problem. It's important for interop reasons that I find a solution. I'm setting up a message forum and its success depends on interactivity between the forum and an IRC channel.

The BrowserFlags registry key was included as part of the HKCR\irc branch in this post. I've removed it and there is no improvement.

I have the URL:IRC Protocol option 'Confirm open after download' checked already as well.
