Whenever I have task which has the same start date and end date, and a duration of one day, and I move it (to a different day) in the Milestone Gantt view, the task will always be changed to a two-day task with the start date unchanged but the end date moved one day into the future.

This is of course very annoying but its even more annoying due to the fact the graphical representation (length of the blue/yellow bar) is not changed.

Best Regards

Johan
