This indeed was the issue. The filename with spaces was being created by the C++ code and the buffer had not been flushed. Adding a flush fixed it. When I was testing with a filename without spaces I was not using a file created by the C++ program. Much thanks to everyone who replied and offered advice and suggestions. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
