2.3.1 is here to quick fix a bunch of reported problems, mainly your Voice problem.
It also fixes the Inventory sort buttons beeing unfunctional, show parcel properties/coordinates missing in topbar menu aswell as the whole mini locationbar which i was originally going to remove entirely aswell as the ability to disable the favoritesbar and removes the worn tab aswell as the misleading 2x/4x/8x/16x Antialiasing types which don't work as FXAA only knows On and Off in SL and it also removes the RLVa menu as RLVa is NOT part of this Viewer anymore, for now.
As always, be sure you delete your settings when coming from pre-2.3.0 versions.
BTW, the world is a Torus type and i found it's end.
Added: Show Parcel Properties and Show Coordinates menu entries to the Topbar menu.
