code works in DW8 but not DW CS3

Why would the following code work in Dreamweaver 8 but not in Dreamweaver CS3?

Expires in
<select name="mnuExpires" id="mnuExpires">
<option value="0"

0</option
option value="30" <% if true then response.write("selected") %
30</option
option value="60"
60</option
option value="90"
90</option
option value="120"
120</option
/select> days.

Dreamweaver CS3 shuts down after throwing an error: "Adobe Dreamweaver CS3 has
encountered a problem and needs to close. We are sorry for the inconvenience."
Event ID 1000 appears in the Application Events Log.

Starting with a new ASP VBScript page, I add a form with a list/menu. I set the list/menu to list and then click the Dynamic... button. Again, DW CS3 blows up as in my first post.
