Ok, bit of an update here... If I select a track (or album / playlist) and play this through to the end, media center seems to handle this fine. If this track (or album / playlist) then finishes, and I use the app to select a new track / album / playlist, it plays, but does not show on the lcd screen on the case and the computer shuts down unexpectedly after 30 mins.
Using MCE standby tool, I can see that when initially playing the first song / album / playlist, media center is seen as active. When this then finishes and I start a new track / album / playlist, media center is seen as idle, hence the shutdown after 30mins. Any idea why this might be?
Thanks
