Copied text within Scrivener turns black when pasted

This just started happening today. When I select text and copy it within a Scrivener project, the subsequent pasted text is black. My project text is white all the way through. What did my finger trouble do now, since I’m renowned for it?

Yes, I know. I can paste to match style, but I didn’t have to do that before today.
Well now, I just did a copy and paste, and the problem appears to have resolved itself. Majick.
