Beginner: how to format my desktop widget

Hi, I have downloaded the trial version of BTT and I'm trying to make a desktop widget. I was able to set it to evaluate my AppleScript and display the resulting text in the widget. However, I cannot seem to format it like I want to. I try to use the Fonts button to select a font, size, and color, but it doesn't take. The text in the widget is still white, not the color I chose, and not the font I chose.

Is this a limitation of the trial version, or a BTT bug, or basic stupidity on my part? :wink:

If I can get this to work the way I want, obviously I will purchase BTT.
