The time of event’s lasting can be changed by using the mouse. First you need to place the cursor over the edge of a fragment representing the event so that the cursor’s arrow is changed into . Then push and hold the mouse left button and then move the said edge into a new position, controlling the move with a clock located in the top left-hand corner of the image.

The line indicating 12:00 – it shows the hour that the program has set on the disk. If the line is not in the middle of the "tear" (Fig. above) it means the program has set it incorrectly or it has been moved by a user (see: Set 12:00 hours)
