How to resize a custom object
Custom fields and draw objects that you add to the header or footer of a report, and some built-in optional header fields that you can add by choosing Report (or Invoice)>Report Options, can be resized to fit text length and design preferences. To resize the field, drag any of the resize handles to the dimensions you desire.

If Grid Snap is turned on, you will need to hold down the Shift key on your keyboard in order to resize the field by dragging.

You can also resize custom fields and draw objects by changing their height and/or width dimensions in the Layout Tools palette. TimeCache only lets you enter values for objects' dimensions that can be changed.
