Unity 4.2 broke the button, because they incorrectly say everything supports multitouch even though it doesnt.

Hi guys,

We ran into the same issue, and we were able to track down the source of the problem. 

The issue is that in Unity < 4.2, Input.multiTouchEnabled returned false in the Unity editor.  Now it returns true.

The workaround is to use preprocessor conditionals.

So change:

#if !UNITY_FLASH
         if (Input.multiTouchEnabled)
...

to

#if !UNITY_FLASH && !(UNITY_EDITOR || UNITY || UNITY_STANDALONE_OSX || UNITY_DASHBOARD_WIDGET || UNITY_STANDALONE_WIN  || UNITY_STANDALONE_LINUX)
...

Will email the fixed file to your support email. 

Thanks again for a great product, guys!
