Blimey Nod32 is getting more and more buggy. Three pc's with latest Thunderbird and with the email scanner enabled you get messages flickering in and out of the inbox for ages. Sometimes it doesn't stop so you have too disable the scanner so you read the messages. If you delete messages the same problem occurs and if you're unlucky you'll end up more and more duplicates of the same email. Sometimes you can't delete emails once that's started you have delete all the msf files and allow Thunderbird to re-create them. Sometimes when you delete messages they flicker in and out of the inbox and then just disappear altogether. Latest nod32 fully updated. Together with the problems we have downloading files from the internet it's getting to stage that I've either got to go back to an old version of nod32 or dump it altogether.
