MoviePlus 5 defaults

I wonder what happened? I notice that whenever I put a new camcorder tape into MoviePlus5, or when I insert JPEG's, or new sounds, they ALL go onto the timeline with "SOLO" selected by default. I have searched and searched to find the setting that I changed, to no avail. I wonder why this fine program has suddenly changed that default setting? And how do I change it back to 'NOT SOLO", that is so it WILL play by default when it is inserted onto the timeline.
If anyone has an explanation please either send e-mail, or let me know that the problem is addressed somewhere.

Thank you for your help
