What version are you using right now? I just found out that they have now abandoned the rendering engine of the older versions and have tagged into the Chrome engine for versions 15 and up; they are up to 18/19 now. (I am using 12.16: wasn’t aware that they had essentially frozen at that version. I wasn’t aware that they had forked...)
They have also taken out the M2 email client and have it as a separate application... Not liking any of this, and may have to stick with the older version, at least until I can figure out what to do...
using 12.15.7 and 11.6.- i was never fond of 12
