Your Mark as Patrolled Script....
From User talk:Blue
It appears from RecentChanges that you modified your .js file recently, you may have to wait for your browser cache to clear.
the edit was a vain attempt to account for Blue's name change, as her userspace was where my .js was fetching the code. a hard refresh didn't help.
Ask User:Ty if he is having problems, he is the only other person who has accounted for the name change. Or maybe the MordantMaenad will know the answer.
It is an issue with the cache. Mine works perfectly.
...Unless you're using IE, as I think it might fail in some of the older versions.
