No Rotation for DoubleSight DS-90U (Lion)
 

I am using a DoubleSight DS-90U with OSX 10.7.3, and the new DisplayLink alpha driver. I get no options to select screen rotation in Display Preferences; only 1024 X 600 resolution is shown as an option. Doing CMD-OPT -click Display does not help.

UPDATE: I was cmd-opt-clicking the "Display" tab within the "Displays" preference selection. You have to cmd-opt-click the "Displays" icon in the Preferences menu. DOH!
