Steinberg have updated Cubase SX to v2.0.2.31 for both Windows and OS X. This version comes with a lot of fixes and enhancements. It also cures the graphical display issue for Mac users on OS X 10.3.x:

Remote controller (Yamaha DM2000v2/01x, Steinberg Houston/ID, Mackie HUI/Control, Radikal SAC-2K, CM Motormix):

• Unused motor fader are moved to lowest position.
• Added "Hold" mode for buttons: Shortly pressing a button toggles it, holding it but pressed longer will turn off the parameter when releasing the button.

• It was not possible to copy and paste events in the tempo track.
