Logic Pro 9 Logic Control - shift/Nudge doesn't stick

On my last version of Logic (5.5:redface:) holding down shift and hitting the nudge button put the Logic Control (and Mackie Extender) into Nudge mode.

All the V-pots could be used to nudge selected objects by ticks bars etc..

On L9, the nudge mode display appears but reverts when releasing the buttons.

Anyone else have this?
