Thanks guys. I'll keep out of the MAC argument ! but am trying to persuade Mrs. ExS to set her browser to auto. delete cookies on exit, or I will occasionally do it myself when I can get near the desktop ( that's why I bought my own laptop ! )

There are many, we are booking a Europe whistle-stop later this year, and she has found hotels, air fares, and presently Eurostar ticket brokers London-Paris who practice this iniquity. Eurostar is particularly evil, apparently - ( I'm keeping out of the exercise at the moment ! ) they appear to make bookings available no more than 6 months ahead, and once posted the price increases by the minute as the tickets are applied for, she is going to be poised, with credit card ready, 1 millisecond after Midnight plus 6 months on the appointed day to get the best rate - so she tells me.

Sounds a good idea, I'll look at that, too.
Thanks again, approaching 80 it's all too much ! I blame Bill Gates.
