When i do an double-click on any hotlink (websites(http:/...)), the mIRC crashes and i have do close than..
my mIRC do not have any type of remote that changes anything with this.. (only on start, and on exit.. no aliases..)

Same here double clicking sometimes hang mIRC but using right click to open the link works.
I use 98SE + mIRC 6.16 + Opera 8.
btw it would be handy if during the time you double click if the link scrolls you don't open the channel status (checking if the first click was on the link).
