when somebody give a Youtube URL & I click on it, it plays but when I switch back to the thread the music stops & the URL is lost. I want to be able to hear the music while I continue the thread.
When you start to make your post, there are two small panes above the main typing pane, the top one labelled (Optional) Enter URL is where you paste in your Youtube link.
Type what you need to type then 'submit answer'.
That's what I've been doing and the clip then embeds as it did with that last one.
Don't quite understand what you mean by 'URLs cut out'.
