The Controls collection cannot be modified because the control contains code blocks

[Joey]

I just upgraded my web site from from version 1.7.2.0 to version 2008.1415 of RadControls for ASP.Net Ajax and now I get this... There are no <script/> tags in my <head/> control. This is clearly an issue with the radcontrols. What is the fix?
