In LR4 there's options in the preferences for setting defaults for an external editor. It also allows you to confirm/change these upon actual export of a file. Because I'm exporting to PSE10, I've indicated each time and in each place that I'd like it to sow 8-bit depth compression. When it opens in PSE it's locked and won't let me do anything until I change from 16-bit to 8-bit (despite the fact that I've repeatedly indicated 8-bit). Is a fix for this expected anytime soon? I've already installed the Release Candidate, and it does not address this issue.
