Win XP home.

After some more work I can see that it'll save any changes done to most of the trees. And if it is done first of all things (before moving it or changing size in the scene).
But it'll not save the allready changed models. Say, if I want to do a new one of one of the adjusted ones.

2nd: Also sometimes in Plant room and I have the 'save new plant' dialog open, it just closes the dialog. If I try again whole Vue quits.

3d: When copying a plant material in material palette (down to the right of window) and pasting it on another plant Vue quits.

All of the above I can reproduce so I figure it may be a bug... or two...
