The issue is most evident when browsing through news stories on the home page. If you click on a news story, read it, then click the back button in your browser to go back to the home page, when you scroll your mouse back down to the news section to click on another story, if you happen to roll over the left menu now, you get one of those expanded view boxes that pop open and block the screen.

An example of the expanded menu experience of the Yahoo Homepage.

As an alternative, you can turn off the left navigation of the Yahoo homepage by clicking the ‘page options’ link and selecting “Switch to Compact View”. This is fine, but I actually like the links on the left, just not the expanded menus that are forced upon me. The compact view goes back to something more resembling the old Yahoo homepage, but its almost like there are miles of difference between the 2 versions. I wish there were a third, middle-of-the-road version that would allow for some hybridization of the two versions.

Update: It appears that Yahoo has listened to all the complaints. They have updated the menus to now allow you to click before they expand.
