I assume by MSN you mean Internet Explorer?
I need more details in order to help you.
Please open Internet Explorer. On the main menubar at the top to the far right it says "Help". Click that, then on the dropdown list select "About Internet Explorer". A small window will pop up. Within that window the version of Internet Explorer is listed. For example, my laptop has:
Quote:Version: 8.0.7600.16385
Please tell me which version you are using.
Having done that, I also need you to explain what "only works about half the time" means. What specific problems are you experiencing?
