I'm either doing something wrong, or a stack isn't what I think it is. if a stack is the fan of folders on the right side in the dock, then when I right-click on one it simply opens the file. and by right-click do you mean the right side of the touchpad? I'm not using a mouse on my MacBook Pro so I'm assuming by right-click you mean the right side of the touchpad. I have tried right clicking on every spot on the stack and I simply do not get an option, or a menu. please forgive me if I am not understanding you correctly, I just do not see the option anywhere.
