about do-Organizer Jun 2011

This application is bulky, slow and overall terrible. It cost over 30.00 dollars and really should have been a freeware. It appears as if it will be feature rich but most of the components are redundant.The graphics are very outdated. I really was disappointed and they give no refunds or apologies toward customer complaints
