We have had problems with IE9 freezing on certain sites (not seen this problem previously). Has happened over the last couple of weeks. At the same time I noticed that some automatic updates were failing to install. which may be just a coincidence. One I have had to hide for the moment is the latest Skype update.
To cut a long story short, we swapped to Chrome a couple of days ago, and we are not seeing any problems at all using it. In fact, my wife is now able to upload stuff to her work website again which she hasn't been able to do from our desktop machine since we "upgraded" to IE9 some time ago.
So not a solution exactly, but it's made our web browsing a whole lot less frustrating
