Title:
  Holding down blank hotkeys for a few seconds crashes OpenLP

Status in OpenLP:
  Fix Committed

Bug description:
  If blank to x hotkey is held for a couple of seconds,
  OpenLP becomes unresponsive and crashes.

  Ideal solution would be to have the code execute only when
  the key is pressed once, not when it's held.

  Win 10 2.4.2 / trunk 2695

  Traceback:

  Usually it crashes before any traceback is created,
