Current Menu Item

Hi Sakin, I have another question: the simple catch themes highlights the current menu items using "current-page-item". However, if the current menu item is connected to a category (in my case, my blog) this menu item is no highlighted like that. Is there a chance to change "current-page-item" into "current-menu-item", so that all current menu items are highlighted? I tried to simply replace it, but that didn't work. Best wishes, Jonathan
