Unwanted tabs added when DVDs are read

I using a Lister with dual horizontal Windows. I have several tabs at the bottom of the Windows. My tabs are all locked. My problem is that every time I load a new CD or DVD a new tab is added. I don't want the new tabs added. Where in the preferences can I fix this issue so I'm not getting all the exit tabs?

Check your Windows autoplay settings.

I did check, I had no idea. This will change the way I do things. Thanks again Leo.
