Hi Eric and all, the brazilian thread said that the guy solved the problem changing the config.sys to : FILES=150 BUFFERS=80 Autoexec: SETCLIPPER=F150 DOSKEY he had other problems but related to internet explorer. tks... ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
