Lost focus always in chat area when delete last word

In chat area.
When I use backspace key to delete last letter last line.
then the focus will be lost in chat area.
but I want put new words in chat area.
so, every time, I must press the mouse in chat area again, then get the focus in chat area.

I misused the function?

Hey, that’s quite strange. Perhaps this shortcut is already assigned to a focus-switching function. Can you check your key bindings? Also, let me know which version of Cursor you’re using and your operating system.

cursor version: 0.45* 0.46*
status: agent, claude-3.7-think…
step:
after submit some requests.
then the result showing, up of the chat area.
when cursor finished the code changing, show the line changed lists of all files.
may be waiting programmer press “accept all” button.
now!!!
write any words in chat area,
then press backspace.
lost focus in chat area when last letter deleted.
till you press “accept all”, the chat focus nomally.
