The orginal post talked about fitting clothes to Dawn, hence my comment.  But yes if you wanted to fit Dawn clothes to G1/2 you would have get a Dawn clone shape and only Hivewire could authorize that.  And since neither of the two parties are interested in playing that game, you are left to having to make your own clone.  So interchange really isn't all that supported. 

As for the content manager causing problems, I don't use it, which solves that problem. I use Advanced Library to manage my content.  Since it works the same with both Poser and DS I get a much more unified view that works with either app the exact same way.  I don't get the pre-generated Content Manager tags though (I have to setup that kind of thing myself in AL).  But AL has much better and faster searching and filtering, even if it is very long in the tooth and not being developed further.  I've never had any problems with the Content Manager working though (I just don't like it). 

When DAZ Studio crashes it will offer up a crash report, looking at it can often offer clues into what exactly went wrong and how.  But DAZ technical support has been kind of weak in the last year.  I doubt anyone that could read your crash report ever sees it.  Didn't used to be that way. 

If you get a crash dialog, press more and look at the Stack Trace.  It shows you what exactly crashed.  Save the crash dump out and open a Zen helpdesk ticket with the crash zip attached.  Do it everytime it crashes and you can get a crash dump. 

My new policy is I'm reporting every single issue with any DAZ product I find.  I'm fairly sure I'm on their list of "annoying" by now but they are fixing things (mostly content bugs, I don't have that many crash issues with DS).  Post a screen shot of the stack trace to this forum, perhaps someone here can offer you some clues.  There are a lot of system things involved in the way Content Manager works (which was a bad design) it's possible that is what is causing your issues.
