Here the applet doesn't use any DisplayText. Coupled with a BgColor that blends the applet into the page background, you can't see anything at all! Try moving the mouse around above the heading...

To make this work, of course, the DisplayText can't be completely blank since it defines where the reactive area of the applet will be. Therefore, the DisplayText has been carefully filled with hard-spaces (ALT+0160) to make the reactive area almost exactly the width of the text in ReactText.

Once again, this applet doesn't link anywhere (although it could if you're sure people would find the link on your page!), and it doesn't make use of DateTrack's modification date-tracking or URL capabilities so it's an unnecessarily large applet to use for this bit of nonsense.
