Setting alpha scale on a disabled DirectButton

I have a quick question on direct buttons:

I’m disabling a list of buttons and then attempting to fade them out before completely hiding them. I am able to do this perfectly if I do not disable the buttons before I fade them, but if I first disable them and then try to set their alpha scale it seems to have no effect. I’ve tried both the top level node of the button, and the disabled state nodepath directly.

Any help is appreciated!

Seems to work OK for me. Can you show a tiny sample program that doesn’t work?
