What's Wrong?

FR : Je vous signale également que quand je suis avec Claude Code, mon clavier fonctionne très mal.
Parfois je n'arrive plus à taper un t ou un m ou mettre en majuscule, ou parfois quand je tape des lettres (et
souventt les mêmes (t, m parentheses ... ) elles se doublent alors que je n'appuie qu'une seule fois. Je ne sais pas
d'où ça vient car cela ne le fait pas dans word, ni dans delphi par exemple.
US :
I should also mention that when I'm using Claude Code, my keyboard malfunctions.
Sometimes I can't type a "t" or an "m," or use uppercase, or sometimes when I type letters (and

often the same ones (t, m, parentheses...)), they double up even though I only press the key once. I don't know
what's causing this because it doesn't happen in Word or Delphi, for example.

What Should Happen?

I expect the keyboard to work normally, quite simply.

Error Messages/Logs

Steps to Reproduce

1 . run cmd, launch Claude code
2 . enter some text, anything. some letters are impossible to enter : very often they are the same : "t", "m", "T", "M" or even ENTER key !!!

Sometimes it's worse; I type the letter 't' once, and it types 2, 3, or even 4 times in a row.
