Originally posted by Kanth Mav, I believe in 98 it's winpopup.exeStart/Settings/Control Panel/ Add Remove Programs/System Tools/ Winpopup (it's at the bottom)edit: unless you've isnstalled msn messenger, I dunno if they included an extra pop up with that, my guess would be that they did and that'd also what they included in their later OS's as the messenger service.
