I've used PM5 and C1 for 6 months now. I am not sure why you need to export something? I have set up C1 as an editor. If I Edit x.arw with C1, then C1 must open, open it's library (assuming it's not running) and then create a dialog to "import" the image. When finished, I use C1 to process the file to another directory. Sometimes the C1 hides the folder after import, and I have to go to the folder tab in C1. No issues at all. Thanks.
