Hi.
If you open the Find window (Cmd+F) then start to type/select anything … then change your mind and close the window.
It leaves the drop down menu in the PG window.
You cant get rid of it.
until you open another find window again and then select a dropdown menu item… to open it, then click it again to close it THEN… close the main find window.
Id expect it to clear up whatever blue dropdown menus were open upon closing the window by clicking the x at the top right, not leave the drop down menus on the main window after closing the find window.
