Sorta bug - B6 Mac exports files with no extension but requires the .br6 extension for Dbl-Click and Drag 'n Drop. I've gotten in the habit of adding it whenever I save a scene file. You can add it later in the Finder but make sure you add it to the .PCT image file as well. i.e.: MyScene.br6 and MyScene.br6.pct Note that adding the extension messes up the auto-increment feature of the Save As... menu item. HTH; Dan
