I can't seem to find any preference that I can set that will allow me to do this. I have to do it manually, or by periodically setting the properties document- or application-wide with everyItem(). But that's not good enough. I need it to be the default.
Hyperlinks used to show up automatically as black rectangles for us, and now they show up invisible. So because I have personally witnessed some change in the default behavior, I feel sure there must be a preference I can set somewhere. But it's possible that was just the switchover from standard behavior in CS4 to standard behavior in CS5.
