    Currently drags and drops works until I press a modifier key like Ctrl or Shift.

    The weird part is when I try to debug using a break point in VS 2010 it starts to work when I resume until a key modifier is pressed again.

    How can I work around this bug?

      What do you mean? What happens when you press these modifier keys?

          IIRC, CTRL on windows changes the drag move operation to a drag copy operation, might be related

            please be more specific! It's impossible to help you when you always say "you cannot" or "it's not working"...

              I was using Qt 4.8.2 on windows 8. It works just fine on my Windows 7 machine.

                Is trying 4.8.5 a possibility ?

                This could be a bug affecting only windows 8
