It always hangs from +/- one minute to forever.
When it hangs, at the left bottom appears what appears to be the culprit, "Transferring Data from the streamer api.finance.yahoo.com". When hung, the Firefox icon (top left corner) changes to a small, empty white square and the curser changes from an arrow to the hourglass for a few seconds, then back to the arrow and icon, and then in a few seconds toggles back and forth. And the progress strip, lower right, is full of green bars. The loading indicator at top right, below red "X", is NOT rotating. If I switch to other tabs or other aps the unit slows WAY down. And after hanging for 5+ minutes and I give up, I sometimes can't close Firefox with red X, and Ctrl/Alt/Del shows "Program not responding" and I close it there.
When (and if) it stops hanging it works fine, as do all other open aps. I have no trouble with other Yahoo sites - or any other sites.
I'm running Win XP Pro, SP2, Pentium II, 450 mhz, 512 memory, 40 GB, Firefox 2.0 (Win IE also loaded, but seldom used) on a 9 year old Dell. I'm not too swift: someone suggested the problem involved Java script (whatever that is) and had me load the "NoScript" ap but it either doesn't help - and/or I don't understand its instructions and use it incorrectly.
If you can help, please go easy on the abbreviations and techspeak. Thanks, in advance!
