Without the auto-tool on, you can't get the little grabby hand to move the block diagram around when the VI is running because (per NI support) they purposely killed the popup menu. Nice. If it's not broke, don't fix it. This has been reported, and the hand is automatically available with the auto-tool on.
The real request here though is simply for horizontal navigation with the roller ball. Currently you can get vertical navigation and fast vertical navigation (hold down Shift), but no horizontal navigation by holding down Control, or Control+Shift, as is used in other programs (Microsoft Visio for example). This feature would make navigation really really easy.
