Hello, I have a problem when I write a new song, every time I write a letter "i" tiny, automatically becomes capital. The problem is only with the letter "i", if attached to the "i" would add another point the problem is not there. What could it be? How could I solve?

Edit > Options > Live/Song > Song Font dropdown menu
Click on the Format tab
Uncheck the box that says "Automatically capitalize first character of these words"

That should allow you to type a lowercase "i" without automatically making it a capital.
