if i remember correctly there is a dll out there that does allow registry manipulation for use in mirc ..... altho i am not positive of its name or where abouts. i once went on a search for dlls for mirc to see what i could find and toy around with..... id have to assume that would be the safest way to manipulate your registry by only having that dll ....... i could only imagine how bad things would be if mirc had it built in to every download that someone could use something similar to that matrix deal to mess up your pc on ya ...... again im thinking its just a dangerous thing to put into mirc from the box but it would be a nice idea to be able to have it at your disposal
