Sorry for the late reply. Tried that and couldn't download addons from the libreELEC repository. Think I've found a work around myself. In the Keymap editor you can assign a button on the remote to reset kodi. When I loose the picture ,I just press that button. This brings back the picture and I don't have to disable and enable the server and HTSP client. This issue doesn't happen often, so I can live with it until it's fixed. Thanks for the help any way.
