OK, I’ve changed the ini file again and it makes no difference.

Just to be sure that it wasn’t anything else trying to connect I un-installed Avast and it stopped. Back to 4.1 now and all ok.

I have none of the boxes (Permaneant or Dial Up) ticked at present and it works fine.

Next I will try going back to 4.5 and try with no boxes ticked. Maybe it gets confused with my always on connection (NTL) ? Will let you know what happens.

Once again thanks for your help and sorry for the misunderstanding.
