I haven't had issues bringing forward power clipped items from previous versions myself (knock on wood).

I have a few versions installed. They all play well with each other, so I don't know what's wrong on that front.

You might want to try some searches on the CorelDraw forums. I have seen a few threads about this, participated on at least one of them.

I don't recall if the last thread was ever resolved for the lady or not (her name is Judy should that help finding the thread). It involved spot colors. Her file was incredibly slow to redraw. I rebuilt the file and it was zippy on my system, and hers if I recall. But I don't know if she was actually able to rebuild it in the same manner and get it to run quickly.
