Hi @Martin_Kraft Thanks for the forum post and sorry about that! This is a known class of issue we are tracking.
First, to reassure you: this isn’t something on your end, and reinstalling wouldn’t have made a difference. We’ve confirmed a real bug in how agent chat tabs are restored, where previously open tabs don’t come back cleanly and you can end up with extra blank “New Agent” tabs. It’s a known issue that we’re tracking and actively looking into.
A couple of things that can help in the meantime:
Instead of Developer: Reload Window, try fully quitting Cursor (Cmd+Q, or File > Exit) and reopening. Restoring from a normal restart tends to preserve tab state more reliably than a window reload.
You can safely close the extra blank “New Agent” tabs. Any of your named conversations are still there and can be reopened from the chat history dropdown (or the sidebar) if they drop out of the top tab group.
We’ll try to keep this thread updated with any relevant information for you!
