I'm on WEBTV,and I find that sometimes I have to log into this site,and others routinely.
When slow viewing or logging on becomes frequent around the web,I found out that by Deleting ALL my Cookies and then reloading those sites cookies, makes a world of difference.
For Musclcar,or anyother WEBTV users,simply go to your Homepage,click on "Help", then click on "Utilities Tool" on the Left hand column.
You will see all your Cookies and parameters there.Just click on the "Delete Cookies" button...and VIOLA...like a brand new Pair of Fresh Underwear,you are Zipping around the web at Break Neck Speed.That is,until you overload up with Cookies again.
