When you press "Pause", did everything stops OK? i.e. image is freezing ant time begins to show from "- 00.0". Sometimes on pause time begins from "-999", or likewise about (but not from beginning - 00.0) and time shifting did not work - this I noticed on many images, but did not notice on OBH. And the reason did not find. From this for me helps only reboot GUI and try to pause secondary
