Jumpy Parts in Revit...

This one comes from Norb and Emy...when you select some parts in Revit (i.e. light fixtures), they shift in different directions. This is a known issue from the Press and Drag tool (located on the view control bar). If this happens, uncheck the Press and Drag option so it's not available.

Autodesk has this as a documented issue, and it just happened here yesterday. Here's the link to the issue -
