On the Programmers SE site, the menu (with links to Questions, Tags, ect) has a line drawn and text changed to red (or gray in meta) when hovering over that menu item. However, the user must hover over the text in the menu item to actually be able to click on the link.
Ergo, if the user hovers over the non-text part (such as the drawn line), there is no active link.
Is this a bug in the way the css is designed for that SE? On all other SE sites, if the menu item changes (when hovering), I know I can click to go to that page; I don't have to hover over the actual text.
Edit: The designers have partially fixed this, but not fully. The whitespace and line directly below the text is clickable, but if you move your mouse to the left or right of the text, the hover effect is active but no link is clickable.
