I have IE in Parallels version 4.0.3847 in a Mac with OS X 10.5.8 and it runs VERY slow... The company's website requires IE but it is not workable. I've tried Firefox and/or Chrome and both work at normal speed, but they are not allowed in the company. I've tried using any combination but IE is very slow... I have registered the company as a trusted site too, however it is still slow... Any suggestions?
