It's been a while now since this thread was set up and I know the s/w issue has been a hot topic throughout.
I'd find it helpful to know what version people are on now and, for those who have managed to get an update, whether it has proved to be better/the same/even worse.
I'd organise a new poll but I'm a dinosaur so it will need someone young, bright and knowledgeable to do that but if we can't find anyone like that maybe @fredgroves could give it another go.
Basically if you haven't got 1890 you've got software problems of some kind... whether it annoys you or not, they are there.
If you were on 17xx or 18xx you can try to get an upgrade now, if you are on 16xx (like me) you'll have to wait.
I've not seen anyone with 1890 report they have problems still (the AC sync thing is a "function" rather than a bug, although I did read of a possible way to get it, at the sacrifice of something else!)
