ChemDraw Chem3D: I can't move an atom with the arrow tool.

I can't move an atom with the arrow tool.

In Chem3D 9.0 and below, it was too easy to accidentally change the model while selecting atoms or rotating the model. In particular, the selection tool would move atoms if the user dragged the mouse. In version 9.0.1, there is now a move tool, which can be used to move objects.
