Don't have time to track this one just yet but will have a look tonight. The
problem is that you will hang if not forcing a refresh on the component.
TComponent.refresh should probably be calling the main event loop force. This
would eliminate his problem.
myprogress.refresh; -> call tcomponent refresh which forces the event loop.
He is hanging because the GTK event loop is not getting called while he is
