Hey, thanks for the report. We’re seeing similar Agents tab freezes on macOS and Windows in recent versions. Please try:

Check settings.json:

• Open Command Palette (CMD+Shift+P) → Preferences: Open User Settings (JSON)
• Look for ”workbench.editor.showTabs": "single"
• If present, change it to ”multiple" or remove the line

Test in Safe Mode:

• Launch from terminal: cursor --disable-extensions to start without extensions
• Switch to Agents mode: does it still freeze?

Also helpful:

• Clear chat history if you have long conversations saved
• Check Activity Monitor during the freeze: what’s the memory usage?
• Does this happen across all projects or only some?
• Does the same happen when switching to Agents with (CMD+E)?

Let me know what helps!

Yes, changing “workbench.editor.showTabs” to “multiple” fixed it

Thank you

Are you working on a fix? I very much enjoy the clean single config. However, I can also confirm that changing “workbench.editor.showTabs” to “multiple” fixed this frustrating bug.
