gb.CrLf is not the end of line. It is gb.Lf only. Maybe the musical note 
is the gb.Cr character at the end of the line?

Mmm. Strange, as normally SelectAll() method and hitting CTRL+A should 
call exactly the same code internally. I will check... Can you send me 
an example of whay you do exactly?

Not at the moment. It is very complex to implement it in the Editor control.

It works like that:

	MyEditor.Flags[Editor.ShowLineNumbers] = True

A bit weird - I admit I should have used real boolean properties!
