IE 8 takes forever to shut down

I'm not really sure why but Internet Explorer takes a long time to close down. When I close down a single tab, the tab closes right away. However when I close down the program it takes forever to shut down, with the first few tabs taking the longest amount of time. I always have three browsers open; IE, Firefox and Chrome.

I tried looking up reasons on the web, but no luck. Just a bunch of real old IE crashing issues or out of date info.

Anyway here is how the top five browsers are doing on the engineering site: Explorer usage continues to decline, while Firefox seems to have stalled. Both browsers seem to be getting hurt by the increase in Chrome usage. Chrome did not exist before 2009.
