Cannot open Chat Window

[mbryzek]

Thanks for reporting a bug you have found in Cursor!
Please add the following info to help us diagnose your issue:

This issue is preventing me from using Cursor.

Recently (~ 2 weeks) - trying to open the new chat window does nothing - no error, no chat window.

Have tried:

• Cmd Shift L
• Cmd Shift P / New Chat

Until today I was able to workaround the issue by deleting the Cursor application and re-installing. As of today this no longer works.

Hi, have you had a look at the keyboard shortcuts? It may help you with the correct one, otherwise you can also change it if you prefer a different one

Cursor – Keyboard Shortcuts

Keyboard shortcuts are working fine - you can see that in the video where I open the menu to select a new chat.

Issue is that the chat window no longer opens

Ah thats good to know. it sounded like an keyboard shortcut issue.

Sorry i cant access the video as corporate firewall restricts access.

I saw others with similar issue and they had following causes:

• They moved chat to editor and then the pane is always empty until you move editor back
• Too many chats in history, needed to export chat to md files and clear history.
• others had issues with vscode/cursor cache (opening new project where chat works confirmed that)
• …

Can you share how to do these suggestions:

• They moved chat to editor and then the pane is always empty until you move editor back
• Too many chats in history, needed to export chat to md files and clear history.
• others had issues with vscode/cursor cache (opening new project where chat works confirmed that)

They moved chat to editor and then the pane is always empty until you move editor back

• This happens if the Chat pane opens empty. You would be able to see the right pane but without any chat inside. press CMD P to open command field, type > and paste Open Compose as Pane then launch it. it will move chat back to the right pane.

• Too many chats in history, needed to export chat to md files and clear history.

• This happens if Cursor gets slow or crashes or cant open chat. The chat history can be backed up using following extension. Then you can rename project and open it in cursor. This will cause the history to be wiped for that project and its clean. Some had this issue that prevented them from using chat.

Built a Cursor Extension to save and share chat and composer history

The team and I over at SpecStory are huge fans of and avid Cursor users. We all use it daily. Many have indicated on the forums and elsewhere that having persistent access to the chat and composer history in your project folder + elsewhere would be a big unlock. We agree! We built an extension that works with Cursor Version: 0.43.6 that allows you to easily save your history to a markdown file that you can locally version and render + share with others if you’d like. Install it from Visual St…

others had issues with vscode/cursor cache (opening new project where chat works confirmed that)

If you open a new project (or create new project and open in new window in cursor), does the chat show there? If yes, then the project itself has an issue.
Otherwise clearing the cache helps.

Additional:

• Indexing issues. check if indexing works and restart it.

• Docu issues. check if some docus have errors, removing and re-adding them helped some users.

Cursor 0.47.5 Using Lots of Resources ... Issue?

Update here; One of the issues is with docs that get stuck into a bad state. If anyone is encountering issues, can you try going to Cursor Settings → Features → Docs and deleting the indexed docs? Especially if they’re stuck in a yello/maintaining/updating state
