This could be a consequence of exhausting your thread pool. > picture->exec(); This suspends the current thread while waiting for the user to interact with the dialog. Because Wt uses a fixed thread pool this invariably leads to problems. The solution is to use the dialog asynchronously, using show() and reacting to its finished() signal. An improvement to %Wt that has been discussed before is to make sure that exec() fails as soon as it is detected that this would lock up the last thread in the thread pool -- but this hasn't been done yet. With the latest git version, we've redesigned parts of Wt, especially w.r.t. to this thread pool (we are now using boost::asio for this), and maybe we can revisit this feature.
