I've recently bought the new 2.8ghz C2 Extreme iMac. When it was ready for collection, i was out of the country, so my sister picked it up for me. So it was sitting in my room for just under a fortnight before i started it up. Since then, i've had 3 issues with the iMac. 1. the first time i started the mac, i noticed there was quite a patch of what seemed like condensation on the inside of the glass at the bottom right hand corner. after a few hours it went away and hasn't appeared since, should i be worried? 2. after i shut down, i noticed that there were several blotches on the screen, largest one is probably 1cm. its definitely on the inside. any chance it will go away? 3. 2 days back, when i was running aperture, the program froze, i couldnt force quit it. and when i tried opening other programs, they would just bounce on the dock and not open. subsequently, when i was caliberating my screen with Spyder2 yesterday, i tried to open system preferences, it would just bounce and not open, couldnt shut down nor force quit. i've been a mac user for around 10 years now, and the 3rd issue is really something i wasnt expecting. could it be the 10.4.10 update? for the 2nd issue, in the event the blotches do not go away, any chance i might get a replacement?
