I wonder if this behaviour exists in the demo 2.4 in Moodle.org? have you tried it there?
Does this work with a standard thtme? Could it be a theme problems?

I have found the issue in the standard theme and about a half dozen others I tried. I haven't checked the demo yet. I will try that and see what happens.
Oh well. Looks like I have to disable ajax to move anything. Dragging and dropping files to upload them to the bottom of topics still works, but that is all I can get to work with ajax. I have to go back to the old system minus ajax to actually move things. Annoying, but I don't see it working on the demos I saw or a new install I did. Something changed between the early 2.3 builds and late 2.3/2.4 builds it seems.
