When I tried OE6 with 98SE I had problems and had to go back to 5.5. It seems to depend on your computer. What is your operating system? If it is lower that XP why not go back to 5.5? Others will tell you that they have had no trouble using OE6 with 98SE, 98, or even 95, well so be it, but I could not run is properly untill I got my new machine with XP Home.
