We've got suitelets with fields inside/outside groups and they all fail to set focus. Even tried in different browsers in case that made a difference, but it didn't. I've added a client script and set focus that way now, so sorted but it's annoying to have to do this. I notice there's an enhancement which I've upvoted, but presumably the 17 votes it's had won't be enough to influence Netsuite any time soon.
