Are there any text objects that contain empty text strings in your scene?

The problem you describe would happen only if a null text string was
processed by the vector output module as the first text string it
encountered. Remember, "first", means after depth sorting, so it may be
hard to figure out exactly what text object is involved.

The first thing I'd do is make a quick check for empty text strings in your
program, and just for now, set them to ' ' or something to see if the
problem goes away. Once you have verified that this is the cause, a better
solution is close at hand. Remember to consider text strings in axis
objects, both tick text and title text. It is not unusual for some
applications (like iTools) to create a text object with an empty string and
use it to set the IDLgrAxis TITLE property, thinking that it will come back
later and change the text without having to see if there was an object there
first.

This bug is fixed in 6.1.1.
