Information saved in favourites forgotten

[dannyfrankszzz]

Hi, I usually leave my computer running all the time.

I have lots of links in my favourites folder that I use frequently.

However, when I woke up this morning and went to my computer and visited some of the sites that I visit on a daily basis i.e. webmail, forums etc, the websites did not remember my details. I have had to re-enter the information for the sites that I regularly visit.

Any idea why this might be? Does IE automatically disable certain cookies after a period of time?
