oldgreg: Please excuse the cobbled together nature of my post. I realise different fonts is annoying.
You could try pasting text with [Shift+Ctrl+V] instead of the usual [Ctrl+V]. Formatting, e.g., fonts, is removed then.
(I prefer not to write anything about the usual whining here in the forum. It would be a waste of time. But if those people in question believe they are helping the share price, they are mistaken. Exactly the opposite is the case. But then, maybe that’s the intention.)
