A prominent southwestern U.S. university gave this software "free" to its graduating student teachers if they would only preview it and comment on it to its developers--Ablesoft. I used it successfully for seven years, then it stopped working on my computer. I tried everything: downloading new system software, downloading the Teacher Toolbox software again. Nothing worked. The software company does not support its product--none of it's versions: 2.0, 3.0, 4.0, 5.0 or 6.0. The software company has disappeared. Too bad its software did not come disappear, too. One software developer told my son that some software companies sell orgive "student copies" to students that are designed to degenerate over time and only last six or seven years. That seems to be the story with this software. Other users on other websites report the same problems.Don't waste your time with it.
