This presentation based on four years of experience acquired by authors while using some geometrical software in college classroom (http://www.math.psu.edu/math471).

During the last five years a couple of wonderfull dynamical geometry software packages emerge the educational software market.

A common opinion is that this recent development in technology will magically reduce difficulties of geometry courses for high school and college students. Our four year experience proved that it's not the case.

It still be resposibility of a teacher to create a new educational environment where students could learn true geometrical subject matter using modern software, while the software itself would be a tool not a subject in geometry course.

Some do's and don't's when using existing software will be discussed, as well as necessity of development of a new so-called active hypertext support of geometrical software.
