As you probably know, I was having problems with IE6.
Now through pure co-incidence when I downloaoded Mozilla I could not connect through my internet connection. I went into help and typed in the error message I was receiving (720). I was told to go to networking- dialup connection- description and change the name of my PC. When I did this everything worked, including IE6. I would never have found this out, had I not downloaded Mozilla. I spent hours trying to find out the problem with IE6. I now have 2 workable brousers.
