Slackware :: 3D Windows Compiz Plugin Isn't Working

I've just finished installing slack on my new computer, and after about 20 minutes of hair-pulling agony, I've gotten compiz working properly except for one plugin; the 3D windows plugin (windows hover over cube on rotate). I think it might be a corrupted ccsm- whenever I check the box next to the plugin, then try to rotate the cube, it is unchecked. Anyway, I know my graphics card (Geforce 6200 256Mb pci-e) is powerful enough to handle it since the driver installed properly and the effect worked on the knoppix live disk I used for partitioning. I'm running xfce and using emerald as the window decorator if it helps at all. It does the same thing with both animation packs.
