Button tweening to transparent

[Litteratus]

I have a set of buttons that I have set isEnabled to false on startup, and once a network connection has been established, I set isEnabled to true. I also have a UIButtonPlayAnimation disabled initially, so while they are greyed out, they do not do the scale animation like the rest. The problem that I am having is, since the button is initially selected, when the button becomes enabled, it tweens from solid black to a completely alpha image. If I were to move the cursor off of the button, and move it back it snaps the button back in to fully opaque.

My question is, is there a better way of disabling a button initially, and enabling it on some event? If not, has anybody else had this issue?

I have uploaded a video showing the problem.

I still haven't figured out what's going on here.. however it seems to happen when I enable the animation on a disabled button. If I enable(start rendering) the button after the animation has been re-enabled, it starts out fully black, and tweens to transparent. Of course when the animation is re-played, everything pops back in like normal.

Yes, in the initialization of the code, the alpha is set to the tween values at the incorrect location or time and you get bad values.  I have found it is often dependent on what state I start the widgets out in.  IE if they are enabled in the editor prior to playing they have a different behavior than if they are disabled prior to playing. 

To help this out I will set them to a specific state and then use code to automatically set them.  Warning: script execution order can muck with this!!!
