On my website after viewing the grandchildren categories there is a blank box that is visible when viewing the children categories, I know its a tiny bug, but I would really like to fix it. See picture

Also I want to replace the standard search bar with a Google AdSense bar. I've tried to figure out how to do it by reading forums but I can't comprehend what I read, can someone explain it simply or possibly tell me a plug-in that can do it for me?

Thanks so much for the help.

I do not get the blank box on my PC in Firefox or IE. Can you explain more about what you are looking to do with Google Adsense. There is a Google search bar and there are Google adsense plugins but I am not sure how they relate.

in Safari on the mac I see 'What Does The Christian Fish Symbol Mean?'

What browser are you using?

@lmilesw I want to replace the search bar in the top right with the Google AdSense search bar that will display ads with the search results.

@ juggledad I use IE8

The glitch only happens after I view the grandchild, then stop hovering over the categories bar and then go back to the child category

I recorded the problem, the video is available here. Thank you so much for your help.

I never noticed that before. I get the same issue in IE8 on my test site. I think I like IE less and less each day.

is it possible to fix?
and can you tell me how to replace the standard bar with a Google AdSense search bar?

it looks like you fixed it. What did you do?

Ok, lets go back to basics - what version of Atahualpa and WP?
if you are on 3.5.3 - do you have the menu bugfix's installed? (see New Versions & Updates forum)

It's not fixed.
I'm using WordPress version 3.0.3 and Atahualpa version 3.4.9
