TAdvLabelEdit cannot be deactivated

I have several AdvLabelEdit in one Panel. But only one can be active.
AdvLabelEdit.Enabled := False does not deactivate the edit button.
What am I doing wrong?

I retested this here and the button is disabled. Clicking it does nothing.
I guess you refer to the way the button is painted, i.e. that it is not grayed or are you referring to something else?

Yes, it works in the Object Inspector: Enablet = False.
But it doesn't work at runtime: AdvLabelEdit.Enabled := False;.

Ok, this information was essential.
We traced & solved this issue. The next update will address this.
