Ahem, I work Technical Support for a major ISP... I routinely tell people about the advantages of cleaning out their Temporary Internet files (etc.) Maybe the Renderosity system is just having troubles dealing with the new changes, and will get over it?! I routinely have more than one browser window open. That's multi-tasking! I might be at free stuff and the Poser forums. Or I might be checking out my own site at the same time. I have Internet Explorer 6, and Windows XP.... A great combination!
