Below is an image where, upon using 'Set Macro or Group Enable + Show Palette of Macros,' the Palette briefly appears but automatically disappears when the state of the manipulated Macro changes. Is this a bug?
Any change to macros will close the “for one action” style palettes.
It's possible there is some amount of asynchronicity in the Toggle Enabled action, since it changes the macros from the engine (generally only the editor can change the macros and this is an exception).
