UIButton firing multiple times

[nad]

Hey there,

I'm having an issue with some buttons firing multiple times, using NGUI 3.8.1 & Unity 4.6.3.p3. I've attached screenshots of how the UIButton's and UICamera are set up, and below some info from my Console:

1. Frame:23819
2. CharacterButtonUIItem:OnPress() (at Assets/Scripts/UI/UIItems/CharacterButtonUIItem.cs:11)
3. UnityEngine.GameObject:SendMessage(String, Object, SendMessageOptions)
4. UICamera:Notify(GameObject, String, Object) (at Assets/NGUI/Scripts/UI/UICamera.cs:1080)
5. UICamera:ProcessPress(Boolean, Single, Single) (at Assets/NGUI/Scripts/UI/UICamera.cs:1759)
6. UICamera:ProcessTouch(Boolean, Boolean) (at Assets/NGUI/Scripts/UI/UICamera.cs:1942)
7. UICamera:ProcessMouse() (at Assets/NGUI/Scripts/UI/UICamera.cs:1447)
8. UICamera:ProcessTouches() (at Assets/NGUI/Scripts/UI/UICamera.cs:1567)
9. UICamera:Update() (at Assets/NGUI/Scripts/UI/UICamera.cs:1229)

Any idea what's causing this to happen?

OnPress event gets fired twice. First with a 'true' passed in (pressed), then with a 'false' (released).
