look at this a different way. Your say you have had loads of problems with Internet Explorer 6.
Problems with Ie 6 are a sign your software be it either windows or the registry are damaged in some way. putting on a replacment internet browser could cos havoc and crash your machine worst case senario.
Perosnally and hopefully others will agree don't ingore problems and try to take short cuts to get arround, fix the problem or your may be finding big crash or more problems round the corner.
So which windows do you run ?
