First time it happened to me. I wasn't able to set my phone to vibrate before going to work. I was pressing the up and down volume key of the phone and no 'volume window' appeared. Soft reset fixed it.
Love this version of Opera. The scrolling is very nice. There's just the scrolling issue with the Favorites window...
Also guys, do you know if there's a way to change the wallpaper but only in the home tab ? I tried with Menu - Home Wallpaper - Weather Wallpaper and choose mine but it is present in all the tabs
