Download descriptions disappear

[Frogger27]

This is new for me, but it's happened a few times now...
Newsbin is normally minimized, but on occasion when I restore the window position, the download list will be empty.
I can see by the activity on my download monitor that there's still stuff coming in and newsbin itself displays the speed of the connection and accumulated bytes, but the list is empty. I have to stop/restart newsbin to repopulate it.
Newsbin 6.34 on Windows 7.
