Recently I purchased a computer running Windows 7 64-bit and when using Internet Explorer 9 it intermittently freezes and does not allow me to go back, change tabs, or close tabs.

I only use the internet to visit known “trusted” sites such as Flickr, camera sites, Wikipedia, and internet banking. (more…)
