Thanks for the reply. Well I hope that's not the problem (don't want to have to go and get it repaired

) but I suppose it's a plausible explanation. I don't actually use the built in mouse though - I have a USB mouse - and all of the buttons work as expected. They are all raised somewhat and so I don't see how something could have been misplaced. Something weird though, if say I bang my desk quite hard it brings up the menu...so this would suggest something is misplaced like you say.
