We start the process detached (impresscontroller.py):

            cmd = get_uno_command()
            self.process = QtCore.QProcess()
            self.process.startDetached(cmd)
            self.process.waitForStarted()

The waitForStarted call causes openlp to wait for the start. Maybe this
helps.

Title:
  Presentation plugin slows down application start up

Status in OpenLP - Worship Presentation Software:
  New

Bug description:
  Hello,

  On our church computer (XP) OpenLP takes very long to load. (If more
  precious specifications are needed I can provide them.)

  I looked at the attached debug log and found that the presentation
  plugin causes a delay by almost one minute. Here the related lines:

  2011-08-07 09:23:57,000 openlp.plugins.presentations.lib.impresscontroller      DEBUG    get_com_servicemanager openoffice
  2011-08-07 09:24:48,358 openlp.plugins.presentations.lib.impresscontroller      WARNING  Failed to get COM service manager. Impress Controller has been disabled

  NOTE: Due to the long loading time I often terminate the soffice
  process (also I did this time). So it is possible that it delays the
  start up even more.

  I noticed that the start up is only delayed the first time. If I close
  OpenLP and start it again it starts much faster.

  Cheers
