well, I can report that PhilC's clothing room helper seems to work fine on v3MFD, but on Gown for Maddie3, it just draped (with active progress bar) for 19 hours before I finally used task manager to terminate Poser 6.
One thing I didn't expect to happen  (when applying CRH python buttons) was a popupwindowmessage that prompted me to change my end frame to 1 (iow, delete 29 frames from my default 30)...so I did.

The reasons I let it go to see if it would finish must be obvious to the strong user :)
That I will be looking into this more is also obvious, heh.
Today I will be trying the CRHelper on MFD expansion after I use WWizard, to go from V3 to Maddie3.
Any insights would be enormously appreciated. 
BTW I paid some attention to being sure the Gown was "big enuf", so that shouldn't have been the cause of the failure.
Also, am running P6,  2 gig ram 3ghz heart on XP, so... >19 hours seems a tad unreasonable.
