Vegas 12 dialog box issue

Hi

I'm working with Vegas Pro 12.  I can drop a "Sample Text" selection onto a video track, but the dialog box that would allow me to edit (text, font size, color, etc) doesn't open, even when I right click the edit button on the event and choose "Edit Generated Media."  It worked for a previous project, although it was very annoying that the dialog box appeared below the project viewer screen. So I had to keep lowering and raising the frame to be able to see the resuls of my edits.  Now I don't even get that.  Pan/Crop andFX dialog boxes DO appear, but they won't switch for text.

I'm not a pro, but I'm the best the Salvation Army has at the moment. Can anyone help me?  Is there a setting that I'm not seeing?
