Thanks Aren!

Assets/NGUI/Scripts/UI/UIInput.cs(1126,29): error CS0103: The name `mKeyboard' does not exist in the current context
Threw the above error on UIInput.cs regarding the keyboard, have commented the below lines out from OnPress and now all seems to be ok. Guess I'll deal with keyboard errors if & when

/*#if UNITY_WP8 || UNITY_WP_8_1
if (mKeyboard != null) mKeyboard.active = true;
#endif */
Thanks again!
