Is is possible to stop openning new agent sidebar everytime I lanched a new Cursor window?
No matter if I am in editor mode or not. Everytime I open a new window, such as new launch of cursor, open a new project, the “New Agent” sidebar always showed up, and it’s buggy, sometime it has several blank sidebars openned with it, close new agent sidebar will closed them all.
Can we stop this behavior? Is it a purpose to nag user so that we can use the agents features by cursor?
Hey, thanks for the report. The Agents sidebar opening by itself in a new window is a known bug, it’s on our radar, but we don’t have an ETA yet. Another thread with the same symptom: Agents Panel defaults open no matter what I do
One more thing, “several blank sidebars” when opening sounds like more than normal behavior. If you can, please share a short screencast or screenshots right when you see multiple empty tabs. I want to confirm it’s the same issue and not a separate regression. A Request ID would also help just in case. You don’t need Cursor Settings (not VS Code settings) > Network > Run Diagnostics for this one, it’s UI-only. Also please confirm it reproduces on a fresh Cursor launch, not after reloading the window.
Thanks for the reply. For the multi blank sidebar window aside New Agent sidebar, it’s not showing up all the time, but I will make a screenshot and get infomation you need next time I hit it.
Here came the sample, this time, only has one blank sidebar right to the new agent sidebar, sometime, there might be two/three, closing new agent sidebar will close them all.
Got it, thanks for the screenshot. It confirms what I needed to see. The empty panel next to the New Agent sidebar, and the case where there are 2 to 3 of them, looks like a separate issue from the one I mentioned earlier where New Agent always opens. It might be a regression of an older fix.
A couple more questions to narrow it down:
Does this happen on a fresh Cursor launch, or only after Reload Window or opening a new project in an already running instance?
You’re on the Nightly branch 3.3.8. If you ever switch to Stable, please let me know whether the duplicates show up there too. I’m not asking you to switch, it’s just useful info if you do.
Once I have this info, I can route the duplicate panels issue separately.
Following up - version 3.3.30 adds a new “Open Agents Window on startup” toggle in Cursor Settings > Agents. Turn it off to prevent the Agents Window from opening on launch.
To get the update: Cmd/Ctrl+Shift+P > Attempt Update, then restart Cursor.
If you don’t see the toggle after updating, Shift+Cmd+N (Mac) / Shift+Ctrl+N (Windows/Linux) will open the Editor window directly. The update is rolling out gradually, so it may take a bit to reach everyone.
