Cant type in codeeditor

Only cursor keys work in all codeeditor windows even in fx editor.
Have Win7 x64 .net 4 and cant downgrade to 3.5.
Any idea?

since beta24 all effects and dynamic nodes shipping with vvvv are readonly. you see a + after the filename in the codeeditors tabs. in order to modify any of those examples you first have to clone them via CTRL+Enter or CTRL+LeftClick in the nodebrowser.

Big Danke! I was sure i’ve missed something basic.
