Can't scan in Lab

[Snakehead]

The Silverfast document that comes with the Silverfast SE software tells me that I can scan in Lab by doing the following.

16. Select the Colour Model
By pressing the ?command? key and clicking the ?Scan? button a pop-up
allows you to select the output colour model (PC users click with the right
mouse button on Scan RGB key): RGB, ColorSync, Cie-Lab, P&P CMYK.
After the selection is done, the scan button changes accordingly. Default is ?Scan RGB?.[i]

I don't get the pop-up window by following the above. I've tried reinstalling the software.
Help!
Silverfast SE v6.4.1r2, OSX 10.3.7, 400MHz G4[/i]
