The zoom button disappears before I can select the new zoom level (e.g. 40%) To repeat: 1. Press magnifying glass on left 2. Press the xx% dropdown button, a list of percentages appears 3. Move mouse down to select one of the percentages. NOTE: this does not work. The dropdown menu disappears when the mouse moves down. I'm using Windows 7 with Chrome, this happened for the first time 3/22, never had this problem before
