Here is what the "Add Highlight" window looks like :
My understanding is that if I leave the color to

which is not a color, it would used the default color set to "Highlight text" in the mIRC Colors window. It is not so, the color remains black regardless of the color set as default in the mIRC Colors window.
Is my understanding wrong or is it a bug? I am still waiting for a reply on the purpose of "Highlight Text" in the mIRC Colors window.
