Be careful not to draw lines connecting task boxes in LisaProject sloppily.
For example, if you have 3 tasks that are supposed to follow one another,
don't draw a line directly from the first task to the third; otherwise,
the middle task may incorrectly be assigned the start date of the first
task. In such a case, the second task may appear connected to other tasks
when it really isn't. To avoid this problem, first connect the second task
to the first, then connect the third task to the second.
