I was able to get it working... a fair bit of trial and error, and a tip from an Ubuntu post with similar issue...
From a fresh Mint 11 install...
Open Compiz Manger > Desktop > Enable Desktop Cube
Desktop Wall will complain > Disable Desktop Wall
You Compiz & window settings are now hosed > Don't Fret
Compiz Manager should still be open...
Select General > General Options > Desktop Size
Set Horizontal to 4 (Cube) ... set both Vertical Virtual and Number of Desktops to 1
Go back to Compiz > Desktops > Enable Rotate Cube (Don't configure yet)
Now back to Compiz > Effects > Enable Window Decoration (Don't configure yet)
Finally back to Compiz > Window Management
From here enable your standard items such as Move Window, Resize, Maximumize etc....
It wont work yet... but you're close...Now Restart...
It should work from here on and you can enable all the other eye candy as usual etc...
Here's a link to my new install... looks ok for a vanilla load;
