Collective, does that have an affect on links from browsers?
Yes, which is why I suggested it. The effect is making them work at all.
I'd think that option (and from the help file, I'd still think it) is for irc:// links in a channel or msg or whatever.
mIRC doesn't support irc:// links in it's own windows (unless you script it).
fallyhag: Make sure you enable Chat Links
, as I said. If they already are enabled then disable them, close the options window, and enable them again.
