Use of constants and the Sandbox environment

Is there something I need to do to use constants in the Sandbox? At the moment my App behaves differently between Local and Sandbox. Sandbox does not appear to respect the default setting of a constant whereas Local does. Am I doing something dumb?

It should use the default setting that you've configured in your model (which if I recall correctly could actually be different than your local value, which you can override somewhere under settings.. Configurations)

I'd find it unlikely, but if you're sure the default setting is different in your sandbox than your local environment you should file a bug report including the URL of the sandbox and your model.
