Apparently the problem was where and by whom it was called. It was being called from a callback funtion for EnumDisplayMonitors and when station is locked it does not work, and it does indeed fail on new QFile(“some.txt”) line, that I’m sure of it because the next line is if(!file.exists()) qDebug() << “File Does not exist”; and it outputs “device not open” before “File Does not exist”. So it fails on new QFile(“some.txt”) Best Regards, Emre Besirik _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
