Sometimes, it's an easy work-around.
If you now use IE, go to www.mozilla.org and download Firefox. If you now use Firefox, try IE.
It might help, and - if not - excludes some possible problems.
I would be grateful for some help as I am having difficulty getting into the 'sign in' section of the web site of a well known bank to set up my internet account. I can access the web page no problem but when I click on the 'sign in' tab there is a delay and then a 'bloop' noise as though pop ups are being blocked. The bank have assured me that there is no problem at their end. I have disabled the pop up blocker for the site and cleared my search history but still no success. Any advice would be really welcome
