I downloaded IE7 initially when it was in Beta Format and did not like it at all so went back to IE6.
I am now using the full version of it and much prefer it.I have tabbed browsing switched off at the moment, might get around to using it but I didn't like it in the Beta version so haven't switched it on yet.
I also have the latest Firefox which is good. I always like to have 2 browsers as sometimes things don't quite loadr properly in IE7, earlier I was buying something on line and with IE I couldn't get past the payment screen as it kept coming up with errors. I tried it again in Firefox and it worked perfectly, not quite sure what the problem is with IE though.
