Updating color & bold on text widget

Hello,
I'm having trouble getting the text widget to work consistently. Sometimes the bold toggle works sometimes it doesn't. Sometimes the color changes via the "T" button and sometimes it doesn't. I look at the tuts but I must be missing something. Most of my time with Upfront is retrying things that look intuitive but are inconsistent. There must be something obvious I've missed. Please advise. I'm trying to hang in there with Upfront,
Thanks,
Byron
