VB style comments don't work about code-prettify HOT 3 CLOSED

I'm seeing the same problem with ASP.NET and VB.NET code containing ' before a 
comment. 

Code: 

''preforms all the calculations to display amortization schedule.
        Protected Sub btnAmortization_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles btnAmortization.Click
                Dim decLoanAmount As Decimal    'variable for the loan amount
                Dim dblInterestRate As Double   'variable for the interest rate
                Dim dblLoanTerm As Double          'variable for the number of months
                Dim strLoanAmount As String      'string from loan amount text box
                strLoanAmount = Me.txtLoanAmount.Text
                Dim strInterestRate As String   'string from interest rate text box
                strInterestRate = Me.txtInterestRate.Text
                Dim strLoanTerm As String          'string from loan term text box
                strLoanTerm = Me.txtLoanTerm.Text * 12

Mike, 

I'm running rev 64 with the lang-vb file and the comments in VB/VB.NET still 
aren't
working. I'm seeing comment highlighting start at the first ' and it doesn't end
until it encounters another '

Attached is a test file, and you can also see it happening here:
