Seems to have started with last update: Second Life 3.2.6 (248086) Jan 19 2012 13:14:05 (Second Life Release) Changing camera constraints or select distance have no effect. Alt + Left mouse button and dragging no longer zooms in and out, only causes view to spin rapidly. Same thing happens in Mouse look, moving the mouse makes the camera aim skyward and spin like crazy.
