Help with anchor tag.

[eluser]Guuulj[/eluser]
Hi guys.
I have a problem with anchor tag.
I have created controller which path is http://localhost/blog/blogcategory/5
When I manually insert that address in address bar, it take me to that page.
On the side nav, i've placed anchor('blog/blogcategory/5', 'Click Here');
and it doesn't work. When I hover the mouse over a link, it prints out the right address.
Any thoughts?
Thanks!
EDIT: It even work when I drag&drop; link to address bar!
