Does this stop you from using Cursor

No - Cursor works, but with this issue

This was fine last week to have both open, but the latest update closes the editor windows if you open the agent window and vice versa. I frequently find it useful to have both open, and this is completely breaking certain work flow patterns I’ve got used to.

I don’t want to be forced into vibe code mode to make use of more advanced agent features in the agent panel.

Hey, you can keep both windows open at the same time. Opening the second one just isn’t very obvious.

From the Agents Window, open the Editor Window via:

  • Shortcut: Ctrl+Shift+N
  • Or Command Palette Ctrl+Shift+P then type Open Editor Window

Going the other way is the same, just use Open Agents Window. After that, they act like two separate windows, and you can switch with Alt+Tab.

If you want the Editor Window to open by default on startup, the thread Set editor as default window Set editor as default window talks about the current behavior and options.

And yeah, the window switching not being very discoverable is a known thing. The team is aware.

The current situation is that opening the proxy window will close the editor window that is already open.

Thanks for confirming. I can reproduce this on my side. In 3.3.27 and later, opening the Agents window from the editor via a shortcut or the title bar closes the original editor window, and that’s not the intended behavior. I’ve logged this for the team to look into. No ETA yet, but I’ll post an update here when I have one.

Since downloading 3.3.27 this doesn’t seem possible any more… This, frankly, sucks as I do a bunch of work in areas of the code I know my agents won’t be touching while they’re running.

Barring that… a way to use an older version?
