Force Tab to highlight on correct page in CMS

[HM666]

Ok I used to have a plugin fix for this but I've lost it

Here is the situation:

I need the tabs on the built in navigation for vBulletin 4.2.2 to highlight the proper tab when I'm viewing that section of the site. THIS_SCRIPT does NOT work. I've tried that it its still not highlighting the tab correctly. I've tried using THIS_SCRIPT and appending the tab to the URL and not appending the tab to the URL neither seem to work. So what I need is a way to force the tab to be highlighted while its in that area of the site. I'm using the vBAdvanced Links Directory and this is the area that it needs to stay highlighted on. I'm pretty sure that since vBAdvanced has been abandoned that its probably the reason for some conflicts but I cannot afford to not use it on the site. So if anyone has a fix for this tab problem please help.
