Re:NSTextField setTextColor: not working as expected

I don't think that's what that's referring to.

I have used colorWithAlphaComponent: in this same manner many, many
times over the years... just not to set the text color of an
NSTextField.

In fact in another class in this same app, I'm doing...

    [[[NSColor blackColor] colorWithAlphaComponent:0.60] set];
    [NSBezierPath strokeRect:rect];

... which works exactly as expected.

The problem is only when trying to use the setTextColor: method of an
NSTextField.
