[Zope] How do I test a version without saving changes?

Hope this is not too stupid a question: How do I test a version without saving changes? When I use the view option from within the management interface I only get to see the 'live' (ie public) version and not the version that I'm working on. thanks - Jason Wong Digital View Ltd 2201 Nanyang Plaza 57 Hung To Road Kwun Tong HONG KONG Tel: +852-2861-3615 Fax: +852-2520-2987 www.digitalview.com
