A passing thought; I've had problems with the new symbology + print manager 
when it took exception to one polygon in my shape file (for no apparent 
reason). This showed up in DebugView, and Andreas spotted it for me. If you ran 
DebugView while playing with the new labels, it might tell you what was wrong a 
little more precisely. (or you could add bits of the log here, and that would 
help someone tell you what was wrong).

-ramon.
