How do I make the background of a logo transparent on a slide?

Question

This seems to be doc'd in the Captivate 7 User Guide, in "Properties of images and rollover images":
ImageTransparent Background Select the color filler icon. All occurrences of one particular color in an image can be made transparent.
...  However, steps to reproduce:
1. Ctl+sh+m to insert image (logo; lots of white background).
2. Double-click image to open image's Properties Inspector.
3. Under image is the following:
4. I open what seems to be the color selector on the right, and select white.
5. I click the eye-dropper icon on the left (which, when I mouse over it, has the tooltip, "Make the selected color transparent."
Expected result: The white background becomes transparent.
Actual result: The white background remains white.
Am I barking up the wrong tree? What is the correct and effective way to render the white background in an image transparent?
Thanks,
Jeff

Let us just say that Adobe UI designer was not in a good mood that day.
If you notice closely, there is a semi-colon between the eye-dropper icon, which indicates that this icon is just a "label". Next to that is a button that you need to click. Click that, you get the color palette which also has the standard Pick Color filler. Select that filler and click the area on the image which you want to make transparent.
Another alternative for this is, save the image in the PNG format and import it into Captivate. This is hassle-free and in my experience is more cleaner.
