Draw Function calls w/ no scene

I am using Performer to run a visual data base. In my draw routine after I
call pfDraw I call a gl program to draw some 2D text. For some reason when
there is nothing to be drawn in the scene (i.e. the eyepoint is looking off
in space and there is no ground or buildings in its view) the gl text is not
drawn, but the routine is being called.
Is there some optimization technique in Performer so that when nothing is in
the viewing area the drawing is not rendered? If so is there a way to turn
off this optimization? Any other suggestions as to why the gl text would not
appear would be appreciated. Thanks.
