Sweet, thank you, played around with the "Equipment" screen (dragging the gun out of belt, dropping it into hand, then dragging it back to belt), now just need to pick up the ammo to see if that works as it should
You can also still reload from the items page, as opposed to the equipment dragging-dropping. So long as the ammunition and weapon are in the same room, you can click on the weapon's 'reload' option, which brings up a screen of available ammunition. Select the ammo, then the message "cannot access weapon" or somesuch appears, but the action has always been successful for me.
Then why would it only load using the old Position page? Had both the gun and ammo in mah hands on the new Position page but ah couldn't figure out how to load the gun (unless it's one of those 'hidden' buttons), and yes, ah tried dragging the ammo from one hand onto the gun in the other hand
