Well, it wasn't there on the 22nd. and it has appeared today - every time I try to read a thread. It also appeared when I decided to write this. Like many others, PPrune is my home page - it's the first thing I want to read when I log on! As nothing else was opened when I logged on at 07.40 this morning and the dreaded O2 popup appeared, it is either coming from the Freeserve ISP or PPrune. From what everybody else has said it looks like it is PPrune and this annoyance it not helping Danny to keep the books straight.
Thanks Capt. Underpants, I shall be installing your recommendation shortly!
