"close all" feature

The "close all" button does not always work as intended. Depending on the platform, you have different problems. Android will ask you if you are sure, and then give you only one choice, CANCEL. Web works fine but, if you have a lot of position open you cannot scroll up the menu to select "profitable, losing, buy, sell". On windows it will turn a darker shade of green, and then it's not working at all. A fix would be great.
