There's an option to disable.. eh, "convential" sheet notation, but I can't find an option to disable tablature. There's some people that learned to play guitar using "conventional" notation and being able to disable it would make tuxguitar also useful, for, say, piano.
There is an option "View -> Show Tablature", just disable it.
it's not visible at toolbar because some reasons:
1_ we don't have an icon for that :)
2_ score support, is very simple. so it may be hard to "edit" songs hidding the tablature..

Yes i know it, but the main purpose of tuxguitar is to be a "multitrack tablature editor" as the description says.
If you are looking for a powerfull "score" editor, i suggest you rosegarden.
