Tab key stops working after first autocomplete done

Bug Reports

Describe the Bug

For some reason when I open a file and use press the tab butto to autocomplete things the tab key just stops working after one autocomplete.

It stops even adding space (like non-ai IDEs). Simply nothing happens when I press the tab key.
Closing the file and opening doesn’t fix the issue so I have to quit cursor and open it again to get the tab key to work again

Steps to Reproduce

  • open a file in cursor with existing code
  • make the existing code all about Ducks
  • manually changed the first “Duck” variable to “Cat” so now the autocomplete should get it and start wanting to replace all the ducks to cats
  • After pressing tab for the first time to do the first autocomplete, my tab key just stops doing anything.

Expected Behavior

The tab button should work fine even if I’m offline (with no auto-complete) it should at least add space (the default IDE behavior).

Does this stop you from using Cursor

No - Cursor works, but with this issue

Ok I noticed this happens when Cursor thinks there’s autocomplete changes needed in another file so it wants me to jump to that file with “tab” but I’m already in that file. And this popup is just stuck in all files.

It seems there’s no option to disable auto-complete across files (the part where it will jump to another file to autocomplete it)

Hey, thanks for the report. We’ll investigate it.
