So OK installed this Beta version of S&D, so does this program update itself to a later version? or to the final version? OR do I need to uninstall each beta release to install another newer one?

Also I don't see where this beta does its updates, in 1.6 it has a separate screen that pops up that shows me if its downloading or if there are any updates. I tried the Update icon, but it goes to a screen with a listing, that doesn't do anything, the update button when clicked brings up a small pop up which just disappears in a sec, nothing to tell me if there are any updates or not or if its even updating.

BTW I use a dial up ISP (Juno) so downloading the main program if it needs reinstalling takes a bit of time.
