Hello every body,

Before posting my post here, I have searched a reasonable answer on windows XP forum, without any results so that's why I am now focusing on my application.

As I said in my post title, does a PC reboot could be one of the multiple undefined behaviour of QMutex use ?

I ask the question because I have an application wich has a HMI object, before and after each use of this object I use a QMutex that I lock and unlock. I use mutex to protect my HMI object because multiple threads can access it.

Do you think it could be the reason why my PC reboot ?

Thanks in advance.
