I have an issue when adding a new article to an existing page. (ver 1.7.2.471)
I am trying to change the selected text (image #1) to a 'Heading' but the previous article text also changes to the new text style (image #2)
This is also happening in the Beta version 1.7.3.475
This is a new issue, I have not changed anything on my computer.
Thanks for any ideas.
