 * Microsoft Project for the Macintosh, version 3.0

SYMPTOMS
In Microsoft Project, when you drag a task on the Gantt Chart, and the task is 100-percent complete, the duration changes.

Note that this behavior also occurs when you change the Actual Start date for a task that has been completed. This behavior also affects Work and Cost information for the task.

WORKAROUND
If you want to move a completed task, or change the Actual Start date for a completed task without changing the duration, temporarily change the % Complete value to less than 100%. After you move the task, change the % Complete value back to 100%.

STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

Steps to Reproduce Behavior in version 4.0

 * 1) In a new project, choose Gantt Chart from the View menu. Enter a task, T1. In the Duration column, type 2d and in the Start column, type Monday.
 * 2) Select T1, and choose Task Information from the Insert menu. Select the General tab, and in the Percent Complete box, type 100 and choose OK.
 * 3) Drag the task on the Gantt chart to the following Friday.

The task now has a duration of 1 day (1d), instead of the original duration of 2 days.
