There could be two reasons 1. Improper lay out of the report (if you have items horizontally aligned, all the items should have the 'left' property set correctly) Example : Say, You have Items A, B, C, D. Width of these items are 20, 30, 40, 50. Then the 'left' property should be 0, 20, 50, 90 respectively (one item starts after another item) This is a simple case. You should check all your components all properties. 2. If you are using a cross tab, all of your your column group header's position shoud be set to have 'Streched'.
