OS 10.5.6 - Vue Complete - Ver 7.20-04 build 38774
Mouse - Logitech laser mouse, also tried microsoft and kensington mice

My results were the same as Gini's

Drop test
Left Click = reg drop (remains tilted)
Right Click = smart drop (cylinder rotated to land flat)

Load Test
with the already in the scene cylinder selected: Left =load obj , right =save obj.
with absolutely nothing already selected  left=load obj, right = no choice offered

All worked fine.
