By running the step in a different thread, what do you mean exactly ?

As a side note: "Although
QObject<http://doc.qt.nokia.com/stable/qobject.html>is reentrant, the
GUI classes, notably
QWidget <http://doc.qt.nokia.com/stable/qwidget.html> and all its
subclasses, are not reentrant. They can only be used from the main thread."
See http://doc.qt.nokia.com/stable/threads-qobject.html

Would it be possible for you to share some code ? May a topic on your CTK
fork ?
