Problem with RadAjaxManager after upgrade

[Sam]

After upgrading from 2015.3.930.45 to 2016.2.607.45 I get an error when using RadAjaxManager.ResponseScripts.Add

If I rollback the upgrade, it works fine.

I've tried using ScriptManager.RegisterStartupScript instead of RadAjaxManager.ResponseScripts.Add and I don't get an error, but it still doesn't work.

Attached is the error when scripts are combined and when they are not.

Any ideas?  Again, it works fine if I rollback the update.

Thanks,

Sam

The script is just a call to a javascript function:

 

        Me.RadAjaxManagerMain.ResponseScripts.Add("OpenRadWindow('" & Title & "','" & URL & "'," & Height & "," & Width & ", " & IsModal.ToString().ToLower() & ");")
