FrameMaker 9 Paragraph Designer Problem

[Eduardo F. Cidade Sr.]

Good morning to my fellow Frame Templars

Here's the setup:  WXP, SP3, Frame 9.0p237 (unstructured)

Problem:

At any given time, the Paragraph Designer "quits."  It displays when called upon and works 
and that's all well and good but without notice suddenly becomes non-functioning.

This happens without warning and under any one of given scenarios:  single screen, multiple 
screens, you name it.

Anyone have a clue?

Thanks
