It's a cache issue... just refresh multiple times, or force clear the cache in your browser.
I have the same problem, and usually refreshing the page a few times (or force reloading by holding SHIFT when you refresh) will often bump the old version out of cache and load it again from scratch.
Tried refresh a few times but it doesn't seem to change things on chrome.
Oddly though some sort of time period does seem to make it update - if I leave it awhile and come back, it seems to update. Which is frustrating when I've still got a small bug in my home made site lock code!
