My computer is now clear of Bugbear worm - thanks to Heather. Apologies again to anyone who received one of its false e-mails claiming to be from me and sympathy to those who were infected before me and passed it on to the rest of us - I was unlucky, PC-cillin wasn't as quick as some other AVs to send the new definition. While it's still doing the rounds I'll try to remember to put the date in the subject line of e-mails that are not via lists. Malcolm Borrowdale (Swinton, Lancs)
