The Spread component reads the Windows regional settings or options, which are set by the user through the Control Panel, but due to variations in how Windows handles those settings, your user might experience unexpected results.
In general in Windows operating systems, the Spread component does not recognize changes made to the Windows regional settings until you restart your development environment or your application or perform any operation that unloads and reloads the current assembly and dependent assemblies. This is because handling the regional settings is very processor intensive. To optimize performance these settings are not checked each time a simple operation is performed.
In most Windows operating systems, the regional options are read from the system registry. In certain situations, Windows does not clear previous regional options when reading changes from the system registry. Be aware of this when working with regional settings.
