And do you use google desktop? If so, I have a simple solution for that. After installing Google Desktop a couple days ago, my Internet Explorer 7 crash everytime I open it. I thought that some of my add-ons (I installed web-dev for IE, stumble-upon) causes this. After a couple days of investigation I found out that when you enable web history indexing on google deskto, it will make the IE crash. To disable it, you simply set preference on your google desktop (right click > preference) to not index the web history, and voila!! IE works like before.
