        Hi
        Its hard to guess at.
        For hanging I often check
        locks/semaphores/ wait states
        also loops of all kinds.

        Do you have idea where in the program it could happen ?
        do you have any logging at all?

          with a debugger attached you can press the pause button and check the callstack.
          This should give some hints which method causes the freezing.

            Hi @raven-worx ,

            there's no development tools installed on kiosks, should I install Qt deveopment enviroment on them ?

            @mrjj

            Unfortunately it can freeze any where on the application.. There is no routine that freezes the application..
