I'm trying to develop a skin. I reasoned that Zimbra Desktop might be the best way to do this, as it's a localized instance of the Zimbra webapp. I've created a skin directory, and customized some settings in skin.properties. Zimbra Desktop claims to have seen my skin's name, and applied it, but it keeps rendering the old skin (the skin I copied to create my own). Is there some cache I need to update to make Zimbra Desktop realize there's new content in the skin folder?
