that is really odd. not sure why it would do that. Like I said I've been using the 32bit app of IE9 ever since I upgraded my computer. I have win7x64 SP1 and my world is "hunkey dorey".
Google ie9 "not responding" and you'll get a ton of results.... now if I could get my "o" key to work all the time I will be set. This HP keyboard is the worst... I have to hit the "o" right in the middle and the "a" and the "L" too, and if I hit the bottom of the spacebar it doesn't respond. I have had to really slow my typing down LOT because of it... but it is fast and good other than that.
Man, I am glad I rolled back to ie8... ie9 is still buggy.
