Regarding the selection, MLCad uses a special buffer which keeps track of
the parts visible on the screen. For all other parts I would have to go
through the list of triangles, lines and quads until I find something in the
rectangle. This can take a long time since you have to check for each point
on the screen within the rectangle, and some bigger models quickly can have
millions of triangles ...
Why don't you use the mpd mode of MLCad. You can define the sections of a
model in a sub-model and use them in the main-model. Clicking on the
sub-model will automatically select all parts of it (as with any normal brick).

I made a mistake when releasing the last bug-fix - it doesn't have a
different version number or anything. The only thing I can say is that I
corrected such a bug and released the bug-fix on my web-page.

Whoooo ... many wishes ...
- Whats about my original question????
