I'm trying to make Error window.
I've added a panel with position.z = -1, and big filled sprite with collider to prevent clicking other UIs.
Of course I put some window components in front of the sprite.
It works well, but in case I use UIButtonKeys script with other UIs, it doesn't.
The activated UI components(like button, input field) still have it's selected status.(so I can move on among those with arrows)
I want it release when my error window pops up.
How can do it?
