I am experiencing an issue with overlapping colliders in NGUI.
The details of the problem are....
I have a NGU panel of options on the right hand side of the screen and the panel contains a list of NGUI buttons. When the user clicks the button for an option the game does some action. This worked for my game but i ran into issue when the number of options in the panel exceeded the height of the panel. So i added a NGUI draggable panel to my options panel. This works as i can scroll up and down to view the options but i can no longer click the NGUI buttons because i assume the collider i use for the draggable panel is overlapping the collider for the buttons.

Can someone please help. How can i get the buttons to work and have a draggable panel

?
