The usual cause: some add-on.
Go into Tools>Manage add-ons. Disable all and see if it's better now. Then one-by-one enable the add-ons you really need until you find the one that causes it. Disable that again.

My laptop continually gives me a message that interet explorer has stopped working.
This happens every time I go from one web site to another and I have to click on "close the program" to get rid of the pop up. Any ideas how to fix this?
I have a Dell Inspiron 1725 running Vista Home Premium
