I am still experiencing my 2 favourite freezes/lockups with the release candidate. - After the MBP sleeps with Win XP running Parallels is locked up with the spinning color wheel. - If I change network locations in MacOS from a wired only setup to a wireless only setup WinXP will freeze. If I try to stop it by quitting Parallels or using the "Power Off Virtual Machine" Parallels will lock up with the spinning color wheel. In either case I need to Force Quit Parallels.
