The install process hangs on a dialog box saying it's doing cleanup. I let it sit for several minutes until the CD stopped spinning for a while, then had to force the bottle to reboot. After that, the programs all run fine - you just don't get any entries in the program listing, so I used the Run command to add them manually. This was on Mac OS X 10.7.3 (Lion) and BBW 5.5 in a winxp bottle.
The Fan Park Encyclopedia crashes right away, though.
