 # BUGS
 
+- abrir o teste numa janela maximizada e que nao permite que o aluno a redimensione/mova.
+- detectar scroll e enviar posição para servidor (analise de scroll para detectar copianço? ou simplesmente para analisar como os alunos percorrem o teste)
+- detectar se janela perde focus e alertar o prof (http://stackoverflow.com/questions/1060008/is-there-a-way-to-detect-if-a-browser-window-is-not-currently-active)
+
 - usar thread.Lock para aceder a variaveis de estado?
 - permitir adicionar imagens nas perguntas.
 - debug mode: log levels not working
