When playing around on the Piano from the Playable Piano mod, I noticed that the chat will open while playing (after pressing any of the keys bound to the chat), while I'm sitting on the piano.

Of course turning the entire mod off fixed the issue, but that's not what I was looking for, so I compared other mods to see if they have the same issue and I found that BetterChat doesn't have that issue.

Would be cool if you found a way to resolve this.
