Martin, Start another java process -XstartOnMainThread that does the OpenGL part from a Swing application? One hang up there though might be that I don’t think java applications that include the java native commands are allowed in the Mac App Store. Another bug due to each command has it’s own unique CFBundleIdentifier but that identifier is always the same and Apple doesn’t allow duplicates in the App Store. Mike
