NormalizeCase not working right

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Setting the SyntaxDocument Syntax File to the vb.net and
typing a procedure into the systaxbox at runtime.
2.
3.

When you are typing a procedure, etc Public Sub...End Sub, the letters are not 
automatically capitalized.
 This is what it should look like:
    Public Sub SomeSub()
        ...
    End Sub

  This is what I see:
    Public sub SomeSub()
        ...
    end sub

What version of the product are you using? On what operating system?
I am using 1.4 version
