The Massive never seems to be found wanting in this regard, so here's a desperate appeal for help. A while ago I sent the enquiry copied below to Acer; they replied saying it was a software issue (erm, thanks for that - even I could have figured that out), and referred me to their 50p per minute help line, helpfully adding that it has no queueing system. Bugger that, thought. So I turn to you - can anyone advise me?

We have an Acer Aspire 5633WLMi. If the laptop is idle for more than a few minutes, an automatic screen saver kicks in, with music (it sounds like Enya, if that helps you know what I'm talking about). It starts even if there is music playing, for example through Spotify, so is very annoying. I've looked everywhere and cannot find a way to stop this happening.
