version 1.0rc1

Hi, I noticed that with Chrome and IE8 in GridPanel controll I have missed icons, as attached. This is fine only with Firefox, and I don't know what is wrong with that? These icons show up while the cursor is over the menu item, and dissapear after cursor is out. Is that know issue ?
