Version 2.2

• Fixed some messages (thanks to Volker Dirr)
• Fixed some bugs (activities duration > 1)
• New hint window (press H to show). Displays data and MinDaysBetweenActivities Constraints of the Activity

• Improved the popupmenu (displays why it's not possible to set an activity in a cell)
• New commands in the popup menu

** Inactive Activity command helps me to erase activities of a teacher who is absent. After that, I clear ALL the activities of the day he is absent, and I save a new fet file.

When I use this new file with fet, I am able to produce a new timetable just for this day (keeping the other days untouched - perhaps with little extra work fixing absent Teacher's min days per week ) !
