I must add that although not having any problems with PCA pages I have been getting the odd page not opening but that is when Browsing for other things.And yes have to press refresh to open them sometimes. So maybe our problems may be linked in some way.
OK, I cleared out completely all sites in POP Up Blocker in IE Options, and I seem to be OK now. I must have blocked something that caused it but there were dozens so I decided to let it start from scratch again. Thanks for the replies I will tick resolved and see how it goes. RP
