1. Choose the Ticker tape tool, and draw a box as big as you want the final banner to be.
2. Select the box, and look at the properties palette (F3)
3. Enter the values for each item:
i) Number of messages: have a single message that repeats, or several different ones that alternate.
ii) Enter the text for hte message, and the URL (internet address or page to go to if the user clicks on the ticker tape) optional I presume.
iii) Frame colour = border of banner (I think)
iv) Background colour
v) text colour
