Commented Issue: does not contain a script with hash code "7311d143/" [26877]

I started getting this exception being thrown in my production environment. Unfortunately, I have not seen it while debugging. This is from a project referencing the toolkit.

System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NotSupportedException: Assembly "AjaxControlToolkit, Version=3.5.40412.0, Culture=neutral, PublicKeyToken=28f01b0e84b6d53e" does not contain a script with hash code "7311d143/".

Comments: This error seems to be because of the usage of the GetHashCode() method in ToolkitScriptManager.cs. GetHashCode() method produces different results for 32-bit and 64-bit systems. When the scriptmanager tries to reach a referenced script using its' hashcode, it fails, giving the above error message. serdar
