Menu is not highlighted when viewing its corresponding page I'm using D7. In it, one of the menu in left sidebar is not highlighted when viewing its corresponding page.  

Case 1 : If I gave the path to the menu link as node/15, it is highlighted but the anonymous user can't see the menu at all. 

Case 2: If the path will be www.sitename.com/blah/blahbla means its not highlighted and the anonymous user can see this menu.

Since that page is not to be accessible by anonymous user, hence this problem?
Can any one help me to get rid of this?
I put a condition for that node and added the style for the menu in the page.tpl.I don't know is this is the right solution.But it worked for me.
