I just set up a brand new out of the box Studio 1735, and already having an issue. It seems that the touch sensitive controls at the top of the keyboard all work except the volume up/down. Down works occasionally but up isn't working at all. I press my finger down on it, tap it, slide across it, nothing. I can turn the volume up and down manually through the volume control, but not with the touch button.
Please help as this is very annoying and dissapointing on a brand new system.
