on both of my computer i have got IE 7 and out the blue about 2 weeks ago the IE 7 update came up. I installed this update on my laptop thinking it just a like a update (like security updates) and then it asked me to restart then a blue screen came up with just a windows saying the progress of the installation, it took about 10 minutes then restared again then felt like nothig had changed. The update was then no longer on the update list.
I got very much the same today. I had a verification problem so contacted the tech people in India, sorted the 57 security downloads I should have had and found IE7 on my PC. I cannot tell if it`s Beta but an hour later I got a security download for IE7 and that`s where I am now. Only thing I can say to you is `you`re not alone out there`. I do not use IE normally, just my ISP`s front page, so if it`s not evident I don`t miss it.
