Hi there, I've figured this out, but I don't think it's sensible UI behaviour, if it's intended.

I've got a saved search folder that just shows items added in the last two weeks. I was trying to drag a few items into a new folder I'd just created and I could not do it. I could drag single items. There were some items I could drag together. Finally realised that I couldn't drag an item if I'd selected it *and* the child pdf.

Is there a reason for this behaviour? Now I know what's going on, I can just collapse all before I try to copy anything into a folder so (so long as I remember!) it's no longer a problem, but I can imagine it stumping other people too
