Where has the opacity slider gone in the color picker? It used to be underneath the color wheel.

Based on some reading of related discussions, and some experimentation on my own system, it looks like the opacity slider only appears in some contexts and programs. For instance, it doesn't show up when I am choosing a font colour in Word 2011 or TextEdit. It does show up when I am choosing a font colour in Omnigraffle.
Some other articles seemed to suggest it was related to whether there was a background behind whatever the colour was being set on - perhaps that makes sense as opacity only affects whether you can see through something, and if there's nothing to see behind it perhaps it is sometimes thought to serve no purpose? Perhaps it only works when the program chooses to support it? Searching Word help for "opacity" returns no results, for instance.
Hope that helps.

Thanks for the information. I wonder if there's any way to override the applications and make the opacity slider always visible. My major annoyance is when I copy-paste text from web sites into applications like Notes: the text will have a background color set by the site, and it seems like there's no way to get rid of it other than setting the opacity to 0 or by first pasting into an application like TextEdit that strips out colors and then re-copying it.
Where is the opacity slider in the color picker?
