... check system requirments. Just about punched in my online order for LR4 when I decided I better check system requirements. Good thing I did since I'm still running XP and according to sys requirements, Vista w/SP2 or Win 7 w/SP1 is required. Planning to upgrade to Windows 7 in the near future, so a bit of a delay for me.
Hopefully this will warn other XP users upgrading to LR4.
