Remaining Cautious

So I believe eM Client has the potential to become a really good mail client, however reading comments here suggests it may have a long way to go for this to happen. I am reasonably happy with it but do suffer from the old " did not close " properly issue and the more niggling issue of regularly being told log in has failed and being required to enter my password again despite eM having saved my password. I do not know if the fault lies with eM or Sky Yahoo. For the moment I am reluctant to subscribe to the paid version and continue to avail of the free Ver 7.
