There is no problem with V4, M4, V3, M3, and other iterations of DAZ models with the exception of Michael, M2, and maybe David. The current Poser build has Height and Genitalia removed from the taskbar menu. Structure has written a script that will reactivate those features and it can be found in the Free Stuff section. So, don't be surprised when you load those ancient figures and can't hide/unhide their privates. Someone thought that feature was useless.
