WDTV Live and YouTube

I use my phone to broadcast a YouTube video onto my TV via my WDTV Live box. If I want to then use the box to watch content from any other source, it is unresponsive and displays a static ‘refresh swirly icon’. I have to unplug the WDTV Live box to reset.

It is using 2.02.32 and says this is the most up to date firmware. Am I missing a config setting or is it a known characteristic/bug/flaw?
