I'm not sure it's the right group either, but until somebody complains I think
it's a good start.

I am working in the ESPRIT project (P1098 for your information) that it was
born out of.  Within the project the software is known as PCE and there has
been papers published by the main author Anjo Anjewierden of the University of
Amsterdam.  References for these papers can be published if you are
interested.

I have been using PCE 1.x, 2.x and soon will be using 3.x.  ProWindows from
what I can make out is based around PCE 1.x so what I say may not match what
you see.  I have yet to see what Quintus have done to PCE 1.0 to make
ProWindows but I am attending the talk at AIL on March 16th at which point I
guess I will find out.

As it happens I was the Author of the text_block class and early versions did
in fact have lots of bugs in them.  In fact I didn't even know that the
text_block class was included in PCE 1.x.  I expect if you report it Quintus
will/should fix it.  The version that I have in PCE 2.2 works fine.
