curious solution?
After a couple more hours of the same problem and plenty of reads of my post with no replies apart from the one it was obviously local to me so I tried on phone with 3G-no problem.All other internet dealings by me and family were normal apart from Intra-CX hence sluggish time taken to look closer to home?A bit of a puzzle with various computers all the same with CX system but happy doing anything else.Finally pulled plug on router and all went back to normal with CX.Hopefully this will get filed away if you read this and find yourself unable to access Cx.
