Davy,
WGT has a blanket policy that has been stated a couple times on the threads, but nothing that gets very specific. Basically it states that anything for personal non-profit use that does not affect the coding of the game play is OK. That is a very dangerous way to handle if, I believe, but that is their choice, not mine. While an auto click meter does not affect their coding and could be a free not for profit download, I can't for the life of me see them allowing an auto clicker to be used at all, much less in a wagered match.
They aren't going to provide a list of devices/programs that are disallowed, as this would do no more than garner interest in them from some of those who have previously never heard of them.
Dozens of threads with tons of suggestions for correcting meter issues, use the search box at the top right to find them, but beware - you better have a couple days with nothing else planned to wade through them all.....
