I spent about 5 minutes working with this program before I gave up.
My reason is not the problem posted below, but because of the user
interface decisions made. I don't know why every new program has to
reinvent something about the user interface. There is a standard call
Common User Interface (CUI) that is even documented by Microsoft,

The one big difference that hit me up side my head was the way the
Cntl key is used counter-intuitively with mouse clicks for
selections. If you click on one item it is selected. If you click on
an second item, it is *added* to the selections. To deselect
something you have to either press the Cntl key while clicking on it
or you have to use the ESC key. I have *never* seen a program use
this sort of selection mechanism. I have seen variations on how you
select multiple, but every other program I have ever worked with, the
default action of clicking a new thing while an old thing was selected
was to deselect the first thing and to select the new thing.

It was more than once that I tried to move some things and ended up
with a mess because extra moves kept happening. Combine this with the
lack of a working undo feature and I ended up rather frustrated and
gave up. I was looking for something that would save me time over a
program like Visio.

I suggest that the author get some references on CUI or better yet,
use some other programs with graphical interfaces and go with the
flow. It is so much more productive than trying to retrain the
world... if you don't believe me, just look down at your keyboard. Do
you think the keyboard layout we all use was a good idea? It's just
easier to continue to use it than it is to retrain everyone that is
using it now.
