Thanks for the additional comments. I couldn't respond last night because we had one heck of a storm in the Peak District and I stayed off-line. I've been doing some checks after remembering that Pest Patrol had "found" Twain-Tech some days ago and I had told PP to delete it. I had come to the conclusion that PP was the culprit but wasn't sure how it was doing it. I'm glad to see that you confirm this. I suppose that I can tell PP to ignore Twain-Tech and all will be well. I read on a forum somewhere that PP is a prolific generator of false positives so I will view it with some care in future.
