as the title says, this closes the subtitle search window if player has stopped playing the file. Currently window stays open and user needs to close it manually.
@jmarshallnz thoughts please if you have a sec. it does seem to "fix" stuff but I am not sure that you would want it in Gotham.... up to you and @t-nelson
Yeah, this isn't really suitable as that's fired off-thread.
The less elegant but 'correct' solution is to add the dialog to the list that are closed already in GUIWindowFullScreen.cpp - see OnDeinitWindow or thereabouts.
