Limited Searches in Yahoo!

What's going on here? I was busily carrying out some keyword reporting in Yahoo when I was rudely interrupted by this page (apologies for the poor image):



















Now this isn't the first time this has happened to me with Yahoo, but normally the page is generated around the 25th search not 20th.

I suppose this takes me back to my previous post: MSN & Yahoo! Search Musters 3.23% Between Them, and pushes me that little bit closer to ditching these peripheral search engines.
