Interface Active/Inactive image

Within the secondary interface the active image remains displayed when playing the animation. I've tried setting it to a blank inactive image too, but this does not work.
Am i missing something?

can you explain this more detailed. I dont really understand what you mean.

I have a button on my secondary interface of which when the mouse enters the area it plays the button animation and then displays the Inventory screen.
I would like the button image to be hidden whilst the button animation plays, but i cannot hide the button image.
I've tried setting the inactive image to be a blank png and then switching to that before playing the animation, but this has no affect on the image shown.
