<p dir="auto">When I'm in a message composer window and I hide the preview pane, I type a few characters, and the preview pane simply reappears. It doesn't appear to be related to any particular key or key combination. I don't suppose anybody else has seen this?</p>

<p dir="auto">By default, when you type a message, it’s just plain text and stays that way <em>unless</em> you type something that Markdown can turn into HTML. Then, the message becomes multi-part and the preview pane appears so you can see what the HTML part will look like.</p>
<p dir="auto">I don’t see anything obvious in your message that would trigger this, but the line at the bottom is obviously an HTML <code style="background-color:#F7F7F7; border-radius:3px; margin:0; padding:0 0.4em" bgcolor="#F7F7F7"><hr></code> and not just a string of text, so maybe it’s something in your signature?</p>

<p dir="auto">I don't use a signature, but you're probably on the right track.</p>

<p dir="auto">In any case, you might want to experiment with the options under Preferences → Composer → Preview: Display.</p>

<p dir="auto">It's set to display the preview "when generating HTML." I don't know why my message should have generated HTML unless <em>all</em> messages generate HMTL when "Markdown" is selected at the top of the message composer window. I'll change the preferences to never display the preview window and that'll probably take care of it. I do want to be able to display the preview manually, so I hope I can still do so when I use that setting.</p>
<p dir="auto">I don't understand the styling settings even after reading the help, so I hope it doesn't have anything to do with those. I use the recommended styling method and the "Generate HTML even if only for styling" box is checked.</p>
