1. I've seen this problem for years now - the 'Back' button often does not work. This is not a problem with the web sites since I can use Google Chrome and not get the same problem. How is it that the Chrome developers have figured this one out and not Microsoft?
2. Often the first time I attempt to go to a site, I get something like 'cannot navigate to...', and I have to attempt a second time and then it works. Again, this is not a problem with other browsers such as Google Chrome.
I can't understand why Microsoft is not interested in fixing these very common problems - I was loyal to Microsoft for years until I couldn't stand it any longer and switched to Chrome for most of my browsing. With every new version of IE I thought that these problems would surely be fixed, but not so.
