Trevor: fixes are coming to the Shell, too, soon :)
If you mathematically intersect 3 non-parallel planes they always intersect in a single point. Consider the case when there are three faces (or groups of parallel faces) in common with a point, p0. To find the direction to move p1, Anim8or intersects 3 planes that are offset by 1 unit in the normal direction of the original planes to find their intersection p1. It uses the vector p0->p1 as the direction and magnitude for the move. This way all three newly formed faces stay parallel to the original faces.
If you add a 4th non-parallel plane it will most likely intersect the planes elsewhere, not at p1, likely forming 3 additional points p1', p1'' and p1'''. No matter what direction you move p0 there will be at least one new face that isn't parallel to the original one.
However if you create 4 new points then the new faces will stay parallel - but there will be a hole in the corner which can be capped with a flat quadralateral after a bit more math, or 2 triangles.
I don't create this extra face. The reason that it seems to work OK now for points with 4 non-parallel face is because a simple averaging of the 4 normals is close to correct for all for in most cases. But it you measure the length that the point moves it's always 1 times the scale where as other points are moved further. In the case of a sphere the angles are all about the same so it still looks good.

Trevor: Yes, of course that's for scene mode :)

Hey, Steve. I have a big and annoying problem. I dunno why, but anim8or start crashing when I'm in sequence mode, animating.... :((( It just freezes and "Not Responding" ... I don't know why.
I go to the desired keyframe, move the IK controllers, then go to another keyframe.
After 6 or 7 moves, it just freezes. I have the latest version. I don't know what to do.
The figure I'm working with for the current project it's not even too hi poly. Usually, I set the subdivisions to 0 and only when rendering I set it to 2 or 3. So, it shouldn't have this problem...
I even waited for the program to respond, but after 15 min of waiting, nothing... Had to ctrl+alt+del to close it... What can I do to prevent this? Please HELP !!!
Btw, When the next release?
This is what I see in "problem details" :

Steve,
Extrude Connected works much better now. Thanks for doing that. I still wish there was a way to avoid having to clean up faces that become inverted when extruded toward one another. Might it be possible to add an option to automatically merge any new points that pass within a certain proximity of one another during extrusion?

Steve:
daniel99: Is this reproducable, or just happens in more or less the same way? Are you playing the animation? I haven't been able to reproduce it so far.
But I have been able to reproduce a hang when you play a sequence or scene in loop mode (Options->LoopScene) by typing <CR> twice, once to start it playing then once again while it's still running, and then click on the menu. This causes Anim8or to stop responding. The same thing happens if you click on the Play button in the toolbar.
