Close a activity with more to do? - by: rakoun

Hello,

I have a question about 'projeqtor'.
When I marked a activity to "done", this activity is taken into account when I recalculate the project. Why?
Do I need to mark this activity to "close" so it will not be taken into account when I recalculte the project?
The problem is that, often, I end activity before the assigned duration.

What can I do?

Regards,
