iTween and NGUI scale issue.

Hi, I have a UIbutton with a UIButtonScale applied to it. On the 'hover' state it should scale up to 1.2. This works fine with just NGUI but if I do any tweens to the button using iTween, the NGUI Tween on the 'hover' no longer scales up but scales to zero instead.

Here is my iTween code:

Code (csharp):

1.  
2. iTween.ScaleFrom(   child.gameObject, iTween.Hash( "x", 0.0f, "y", 0.0f, "time", 1.0f  ) );
3.  

I have found that it is related to the "ScaleFrom", if i use "ScaleTo" it is fine but I have to do multiple tweens to achieve the same result (or set the values manually):

Code (csharp):

1.  
2. iTween.ScaleTo( child.gameObject, iTween.Hash( "x", 0.0f, "y", 0.0f, "time", 0.0f ) );
3. iTween.ScaleTo( child.gameObject, iTween.Hash( "x", 1.0f, "y", 1.0f, "time", 1.0f, "delay", 0.01 ) ); // needs a delay or overrides the old one.
4.  

Any ideas?
