I can only imagine that spaces are being used, but I can't even reproduce that - maybe I'm using the wrong horizontal lines, but I can't insert a space between the bar line and the repeat symbol - the space either goes before the bar line or after the repeat, no matter where I place the cursor...

I guess I should also ask if there happens to be a tutorial or instructions out there that explain the properties of every single button in the interface in detail - so far, I haven't found one apart from the 11 page tutorial that is way too simple for what I need to know...

Thanks!
