Can't rearrange columns in the song list while in filter view

When I'm in the list media view in Songbird I can rearrange the columns of the song list like track number, artist and album by dragging and dropping them. When I'm in the filter view, however, Songbird won't let me move them around at all. I think I used to be able to in version 1.0, but I'm not sure. A work around for the problem is to get the columns how you like them while in list view, and then switch back over to filter view.
