I'm having a hard time seeing how `$.support.boxShadow` would be set to `true` unless another script is doing that. The cluetip plugin only ever sets it to a string. It's also checking for a vendor-prefixed property if the standard one doesn't exist. Maybe that's not so important anymore, but I can't just assume that unprefixed "box-shadow" will work if I'm checking for the vendor-prefixed ones as well. Can you show me where the plugin is exhibiting the problem?
