      I am unable to press more then one qtpushbutton simultaneuously  on a touch screen

      (I'm somewhat new to both qt gui and gui in general, but this requirement seems very basic to me , thus i've labled this as a bug and not a feature request )


      In other words,  I TOUCH-press one pushbutton, BUT I do not release it, 
      then I TOUCH-press another qtpushbutton, but it (the second pushbutton) does not "trigger".

      by "trigger" is mean that there is no visible change in the ui ( it's supposed to change color once pressed) +  it's released() signal is not sent when i release it.

      it's almost as if the default handler for qtpushbutton.pressed() signal blocks the main event loop,but it doesn't , since while I touch-press a button the application responds to mouse movements ( also i've made sure i don't block the event loop myself in a method called on the buttons pressed() signal ) . 

      as far as i can tell my pc+os supports multi-touch.

       Please advise,
