Scripting a password is not exactly secure unless it's a toddler you are protecting mIRC from and then you'd be better off with a passworded screensaver.

I downloaded this script called "Teens Script", just out of curiosity, the other day and the rip protection made me laugh. To get past it I simply took out the supplied mirc.exe which had it's balls hexed off and replaced it with a legal copy. Rip protection gone and script editor buttons now alive and well. People can do the same thing to script files to make the mirc.exe operational. Just delete them or unload them and the password protection goes with it.
