Thanks for your answers so far.
Tried closing and restarting my computer that does not help.
Where do I find the Task manager Ethel, to find how much memory my browser is using? I am on Windows XP.
Could it be anything to do with that pesky red squirrel? When I try to select the Technology page, it loads an orange site.
I also have a suspicion that Answers.com could also be causing a problem but I cannot find it in my Add and Delete list, to enable me to get rid of it.
