Some text blocks not rendering as images

I am publishing a course with Lectora Pro 2008 where I have several text blocks set to render as images when published. Most text blocks render fine others do not. The ones that don't are rendering transparent .gif file.At first I thought the problem was related to whether or not the text block to be rendered had an action attached to it. I have since discovered that actions have no bearing on whether a text block is properly rendering.Any ideas?Thanks, Glenn.
