[Interest] QFile fails on Windows when screen is locked with message "device not open"?

[Emre Besirik]

Hello list,
QFile fails on Windows when screen is locked with message "device not open”?
And it is on new QFile(“somefile.txt”) not on file.open(ReadOnly).
I’ve recently stumbled this problem and not sure the real cause of it and decided to ask you guys.
And I’m sure that this has only started to act like this recently (in all windows version that I tested — 7, 8, 10)
Does any one knows a workaround? Or can you tell me why suddenly it started to act like this? is that because of an update or its a Qt change?

Best Regards,
Emre Besirik
