I got some users who told me that, and that just happened to me.

I copy/pasted the code from the game to the chatbox.
This isn't pasting anything, yet, the "Write a message" dissapears, which means something happened.
And after that, it's impossible to type or sand anything with the chatbox until I reload the page...

So... The mere fact to open the HOST page in online mode kills the chatbox. What's going on???  😠

Ok, so the problem seems to be coming from Ruffle:

ERROR web/src/lib.rs:921 ruffle_web-wasm_extensions.js:1225 Unable to borrow Ruffle instance

Et en plus, le jeu garde le focus, même quand on clique à côté (ex: barre espace sur l'écran VERSUS)

I posted a bug report on Ruffle's github: https://github.com/ruffle-rs/ruffle/issues/17576

In the mean time, avoid to ctrl+c the code

kjarosh already corrected the bug: https://github.com/ruffle-rs/ruffle/pull/17582
Now we'll have to wait for the project to accept that bug fix and the build to be released.

And it's repaired 😎
