Commented Issue: Does not contain a script with hash code error - No Web Farms [25385]

Keep getting the following error. It occures on different pages, and only when certain users work with the site (about 3-5% of the users). We use 64bit OS on the server, we do not use web farms. What can be the reason in this case?

-------------------------------------
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. You may wanna modify the ToolkitScriptManager.cs file to use a more stable hashtag method instead of GetHashCode() method. Status: proposed Impact:low Assigned To: unassigned -> interesting. so nobody cares about this issue? serdar
