Open Laszlo 3.4 has the best text handling right now.
Legals text handling might well still have bugs. If the examples in
the legals developer's guide
http://labs.openlaszlo.org/legals-nightly/docs/guide/
text.html#text.multiline
look different from the examples in the 3.4 version of the
developer's guide
http://labs.openlaszlo.org/trunk-nightly/docs/guide/
text.html#text.multiline
then we've probably got some bugs -- please do report them.
A code sample that works in trunk (3.4) but doesn't work in legals
would be most helpful to identifying and fixing the bugs.
