This is what get printed into the Terminal when I launch ldglite (using
the rename as ldgledit trick). I always use the editing mode because
LDGLite just keeps cycling through the steps of drawing the model over
and over again if I let it start up in the ldglite mode.

To be more specific about this, I can select the parts, but the
highlighting/outlining of the part does not go away when the next part
is selected. Hiding the window doesn't help get rid of the extra
highlights, but choosing a new view (1,2,3,etc) does eliminate the extra
highlights.
After reading your post I tried
./ldgledit -LEDIT -v799,599 mini.dat
and the model didn't display at all until I started selecting the parts.
Then the parts appeared (without studs) and there was no vivible
highlighting. Using
./ldgledit -LEDIT -v750,550 mini.dat
the model didn't display until I started selecting parts, and the
highlighting of the selected parts worked properly (still no studs).
Editing mode = 1{1} when I type -LEDIT option.

To bad my PowerBook doesn't have an "insert" key.
Yes, I am using the 1{0} mode. See above.

Hmm, I don't know. It is possible that I changed a setting while
editing. I still haven't figured out how to back out of a menu
gracefully. I suspect that my keyboard is missing the key I need to get
out of a menu when it doesn't contain the command I want. I'll try to
avoid inadvertantly selecting the options menu next time I use ldglite
and see if I still bump into the same problem.
What happens is that I'll select a part, move it over, rotate it (the
highlighted outline moves), and then select the next part, normally, the
computer pauses and then draws the part in the new position, but
sometimes just leaves the image of the part where it was (though in the
file, the part is in the new position.)

Wish I could help you there. I can poke a new/beta version with a stick
if you want, but I am pretty dense when it comes to the technical

Oh... I forgot one! The mouse rotation doesn't work right. The model
always rotates in the same direction?! Mouse/track pad goes up model
goes up, mouse/track pad goes down model goes up. Same with left and
right. Actually, every once and a while it works correctly for a split
second.
OK how does one forget that the mouse doesn't work? I got so used to
using the number keys as a work around, that I forgot that I might
actually want to rotate the model.
Thanks again,
Chris

Do you see these anomalies in OS X too?
