The current version has a different action when dragging and dropping a surface colour/material. Originally when doing these all-internal walls of the storey would adopt the applied colour, then a version came out which only applied to the single surface and this version it is only all walls within a room/area and not the entire story.

Is this by design? Or is this on my PC only?

Your advice, as always, will be appreciated, as this is very time consuming on a multi-story building, with many rooms/areas.

Kind regards
