Some time or on some merchants havent figured out correctly yet but while i am sellin items like Thropies or useless item that never use with double click or with sell button. Sell section rollin down of window. To next item i wanna sell have to roll up and sell again. Bad side is i have to do this for each items that i wanna sell.
Btw on regular merchants its happenin but on Laurel merchant it not happening. didnt check other merchants
