When i try to change the icon from the setting menu of the whiskermenu plugin, it seems that the program freezes and i have to close the window by pressing "X".
Does this same "hang" happen when you try to change the icon of a launcher on the panel? I have found that the exo icon chooser can appear to hang when you have a large icon theme (like Papirus).
I've directly tried to change icon theme and now i have no problems in selecting the icon. Thanks!!!
