The company my wife works for has an online site for booking hours etc that seems to work only with IE. I've tried Firefox and Opera and neither works so unless they update the software to stop using proprietary IE code we're stuck using IE for that purpose. She's presently still using a Dell PC but sooner or later we'll switch that over to a Mac laptop but we're going to need a solution for that issue. I know we could run IE virtually in parallels but I wondered if IE was functional in OS X ? I found a copy online so we'll see if it even works for her.
