So you are using Comcast's webmail client rather than using a standalone email program like Mail, Entourage, or Thunderbird? You obviously have your reasons, but I highly recommend that you reconsider. In the best of circumstances, webmail can be slow and clumsy. Mail, I love. Most other standalone email clients work nicely.As for the difference between the webmail in Safari and Internet Explorer, my guess is that Comcast uses an IE-specific applet for that browser.
