Command Window - What is this "find" box?

I have one user whose Command Window has this weird "find" box in it...I have no clue what this stupid this is or how to get rid of it.

In the pic it's the bar just above the word "Building". You can't type in the dark green "edit" box...that just shows up at the bottom line. Clicking the black down on the right of the edit box brings up the popup menu. Clicking the left/right arrows on the right of the edit box supposedly finds the next or previous word but it doesn't find anything; a dialog pops up that says basically it searched the whole doc and couldn't find anything. And all the way to the right is zoom bar that "zooms" the size of the text in the command window itself.

What the $@%& is this stupid thing and how does one go about removing this "improvement" to the command line?

Thanks,

Josh
