Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After I upgraded to version 3.9.16 the IDE is switching to the Agents Window upon startup and is not remembering my open projects.

Steps to Reproduce

Switch to Editor Window, open a project, close the IDE. Next time you open it’s switched to Agents Window again.

Expected Behavior

It’s meant to remember my preference and to stop forcing me to use Agents Window.

Operating System

Linux

Hi @alex-vukov!

Thanks for the report. You can customize this behavior.

The new “Open Agents Window on startup” toggle was in my Cursor Settings > Agents yesterday but is not there today. My current version is 3.9.16 and when I attempt an update it says that no updates are available.

Thanks @adaptive_behaviour. Had you toggled it off? We’re tracking a known issue where the setting disappears permanently after toggling off.
