Textarea near grid

I copied new 2.5 runtime to my project. And now I have texarea at the top of the grid. This textarea is in span myGrid - span myGrid-box and has id myGrid-box-focus. Why it appeared? What properties I have to change to hide it?

The textarea element is part of the grid control and it is required to manage keyboard focus and copy/paste operations. Normally it is hidden. Do you have any CSS rules in your stylesheet which apply to all textarea elements and make this one visible?

Please check that you are not using a diferent version of aw.css.
This effect happens when mixing aw.js ver-2.5 with aw.css ver-2.0x
