Hi! There is this handy feature of macOS that whenever your system language support non-latin characters (like "ż" or "ż" in Polish), you can long press the corresponding keyboard key and the system pop-up appears which allows to pick one of letter variants with a number press.

The problem is, this feature gets distracting when combined with the usage of keyboard keys to play music notes in Picotron's SFX Editor. So, when I long-press "z" to play a C note, I get this:

This is not a big issue, since it doesn't prevent me from playing further musical notes. But still, it would be great if it was disabled for Picotron (if possible).
