This has been discussed MANY times before on the old board. When it happened to me, it wasnt due to any network at all or a virus. mIRC just stopped working my scripts. A week later it started again. Since there's been NO WAY to reproduce this, we really havent found a reason WHY it's happenening nor what to do to fix it. The FIRST time I ever saw it happen was with 6.x on my win95 machine. It hasnt happened since, but no clue why it happened in the first place.
