The bbc editor is the one from SMF? Does the standard forum post exhibit the same issue?
No it does not. Btw the ‘ intro text field’. Does not really have a editor I believe...
It’s the one in attached screenshot...
Ooh, nasty. @rjen,
was the text in the intro copied and pasted from the text in the bbc editor above? or was it typed? What happens if you save the article, preview it, and then grab that text from the main article and paste it into the intro?
EDIT: Ignore that last question, I can see it doesn't make a difference. I can replicate the problem on my Laptop using Chrome Window Resizer. Here's a screenshot of an older intro done on my laptop at full screen, and a new one using he window resizer.
And another screenshot, when I go back and visit the edit page via my laptop at normal rez.
