Spaz arm when selecting objects

[Sassanach7]

Not sure when this started happening (sneaking suspicion it was after downloading/installing latest version of Firestorm), but all of a sudden when I select an object, I get the old 'spaz arm' action happening.

Have made sure 'show select beam' is deselected in Build and went into prefs > Move & View and avatar, but nothing seems to be selected that would be causing it.

And it's driving me 100% certifiably loopy.

Absolutely no idea what that has to do with spaz arm movement when selecting objects, but it's the last thing I tried and it worked.
