Does the site try to load twice on your computer? I have two desktops and a Laptop, This as happened on Dial-Up and now on BB using a combination of Win98se and XP operating systems but using Netscape 7.1 on all of them. It cock's, scrolling the Page up and down, until it settles down. I have had this for some time
Mine does simliar (XP SP2 FIREFOX)done it for as long as i can remember the progress bar gets nearly to the end then reverts back loading the page twice, don't have to do anything it just settles into the page,its just like its stuttering for an instant.
