Google Search button in Win7 visible through wow in isboxer

So, I started up ISboxer with the wizard and works ok so far - a bit much to go through :P

But, when I ALT TAB to a browser, it shows the start menu on top of the fullscreen wow on my main screen - which is ok, but then I click on that window to go back to it - The start menu vanishes, but the little search button to the right of it is still there - in my case it's a Google button.

If I swap main wow instance, it vanishes until the next time I get the start menu back.
