hi guyz,
mirc 6.16 is stable with win xp sp1.
although i have my dcc auto-get off.
i have norton 2005 which protects from worms too and i think some1 was trying to access my computer since i got an elert and i blocked it.

the xdccman.exe which i had mentioned earlier was some free game channel which came along the logitechs cd. i uninstalled it. i no longer get that error.

the next thing for me to try enable auto get and see if its stable. thanks.
