Press event not registering when alpha is zero

[turkeypotpie]

I have a background sprite with a collider attached that fills the entire screen.

If I click on it, I correctly receive the OnPress event.

However, if I set the sprite's alpha to zero, I no longer receive the press event.  What would cause this?

When the sprite's alpha is zero, it can no longer capture events because it's effectively hidden.

If you want an invisible area that's capable of capturing events, use a widget instead (ALT+SHIFT+W).

Cool.  Thanks for the help.
