  Maintenance log started on November 20th, 2000 by Laurentiu Cristofor

  Nov. 20th, 2000   - made some style changes
                    - changed text for some labels

  Nov. 21st, 2000   - resized and repositioned widgets

  Nov. 22nd, 2000   - eliminated the password confirmation check
                      on lost focus, it didn't work correctly
                    - eliminated an error that made it impossible to 
                      change the password
