Great, thanks for the info!  I was able to successfully point my fresh 1.2 install at one of the shared accounts, and under the 1.2 install the ACLs work perfectly so I can now make those folders unmovable as I was originally trying to do.  Don't know what was up with the 1.1 install, but that's now a moot point!  Thanks Timo and everyone for your help!
