have to restart downloads

Im totally gonna sound like a noob here and i guess with this program i am, but i cannont figure out how to get downloads to autostart. When i start jd it auto starts 7 downloads, but as each one finishes thats it nothing else happens until all 7 are done. if i click on the stop button and then the start button a new batch of 7 files starts right up until they are done and then i have to click stop and start again.

From which file host are you downloading?

What's the version of your jD?

What's the version of your java environment?

What's your Operating System and its version?
