Some are seeing behavior changes in the viewer. It doesn’t seem anyone knows if they were intentional. Whether they are or are not, some people are not happy.
Ardy Lay describes the problem as:
Expectations:
A) Avatar is expected to stop watching mouse pointer after a short period of mouse inactivity.
B) World Map is expected to close-couple pan with mouse movement and stop panning when mouse motion is stopped, regardless of mouse button state after stop.
Results:
A) Avatar is watching mouse pointer long after mouse pointer motion stops. This defeats a mechanism by which life-like behavior is imparted into avatar motion.
B) World Map exploration is being awkward as the mouse button must be released to stop the map from panning away from the desired view.
These changes start to appear in SL Viewer versions 3.7.3 and 3.7.4. I find them in version 3.7.6.
With the map, I like the change. To see it click on the map part of the World Map and flick the map left or right. Hold the left mouse button down after the drag/flip motion. The map will continue to scroll. How fast you jerk the image does not seem to matter. The map scrolls at the same speed.
You’ll see some odd behavior when you move quickly. I think our hand bounces a bit at the end and that can confuse the map scroller. Try it. You’ll see.
As to the avatar eyes following the mouse, I have mixed feelings. I gave up trying to control the avatar for pictures with that feature. See Strawberry’s recommendations for pose tools. So, this is not much of an issue for me.
