Funnily enough, I was reading this thread yesterday when my explorer (version 5.5) ceased working and I got one of those annoying Microsoft warnings, saying I had to reinstall explorer from my Windows disk.
No way I said, and restarted my PC with my fingers crossed that the warning was wrong. It was. Taking the advice that IE6 was much better and more stable with lots of goodies, I did the download.
Ive had it running nearly nonstop for a day and a half with no problem whatsoever. Wonderful, and I just love the way it squeezes pictures to fit the screen and the new media toolbar.
A big thankyou to those who recommended it, my Explorer problems appear to be over.
