Does this stop you from using Cursor
Sometimes - I can sometimes use Cursor
Hey there!
What you’re describing isn’t intended behavior, and it’s not something you did wrong. When a markdown file is open and you click the Preview / Markdown toggle in the breadcrumb bar, it can act on whatever editor is currently focused. If you’d just been typing in a brand-new chat tab, that chat is what gets swapped out for the preview, which is also why it only happens sometimes.
Two things that help in the meantime:
- Click inside the markdown file first, then click Preview/Markdown. Once the
.md editor itself is focused, the toggle acts on it instead of your chat.
- If it’s a conversation you’ve already started/sent, you can reopen it from your chat history. Only brand-new, unsent chats are lost, so sending or copying a draft before toggling avoids losing it.
We’ve let the team know and this is an issue we’re tracking. I’ll follow up here when there’s an update.
