Thanks Linc for your help,
Hopefully the info below will help work out the problem (mind you - it is a bit scary how much info has been captured).
It has gotten worse - I now cannot even get to sites I regularly access such as LinkedIn. I have now heard of people having similar problems with other browsers and Windows PCs too...sounds like this is something bigger than Safari......
Thanks
