Why does download manager keep popping up

The download manager keeps popping up when I start DTPro, this happens even if I close the download manager window before closing DTPro. It’s not a big deal but it irritates me. Anyone know why this happens?

This typically is the case when unfinished downloads are in the list.

You are quite right. I had something that was on que there. When I removed it the darn thing stopped popping up. I just thought it was showing a history and not a que.
