I use DT to mount images and created a mount-entry to the context menu. After the mount-command a Go-command is set to open the image immediately.
Because DT needs 2-3 sec. for mounting, I always get a "No disc inserted"-popup (which disappears when image is mounted, but I don't like it). So I want to set a delay of 2-3 sec., but I didn't found a command like this.
