In case it would interest somebody someday, this is how I got rid of the Wolfram-Alpha/free-input form button put by default in a notebook with the Default StyleSheet by Mathematica version 8 (I am using the Mac version, but it should be similar on Windows): The code for displaying the annoying button is in the StyleSheet Default.nb (and probably in the other Wolfram StyleSheets - I haven't looked). I have opened the StyleSheet in a text editor and replaced, in the Style Environment Names section: CellInsertionPointCell->FEPrivate`FrontEndResource[ "FEExpressions", "CellInsertionMenu"] by: CellInsertionPointCell->None I saved the file in the text editor, opened it in Mathematica 8 and saved it from Mathematica as Default.nb. I then copied this modified file to the StyleSheets folder inside the Mathematica application package. Now my newly created notebooks with the Default StyleSheet do not show the plus sign button for Wolfram-Alpha and I am back to the clean old interface. So far everything works as expected, no crashes. We'll see.
