No, I tried. It didn't change. I've 'solved' my problem by working in inches in the Component Attributes. As long as the user sees his own units in the Component Properties (which is the case), it's fine with me, for now.
The problem in the second post is more irritating though. But it seems to be OS related, for it happens only on my Win-Vista machine, and not on the mac I borrowed. Sadly, I only have a license on my windows machine, and not on the mac, so I had to put up with the 8 hour time limit.
I'm able to put properties on to child components by opening them in such a way that the parent component is not displayed in the Comp. Attr. window. But that sucks, cause I loose the ability to click-reference parent properties. Type type type. Bah.
