A ColdFusion 8 project was running under Windows server 2003 which was upgraded to Windows server 2008.
The project has frames and client variables stored in the registry.
After the Windows upgrade, a few users have had client variables disappear. The variables are assigned and displayed in a template in a frame but lost after being submitted to another template in another frame.
The users get an error that "element xx in undefined in client".
What are possible causes and solutions?
