Hi there, I currently use one of the new 24" iMac's. I live in england and the weather has been incredibly hot recently, encouraging annoying bugs known as thunder flies to come out and attract themselves to anything remotely bright. Anyway, the annoying little things have found a way inside my mac and are behind my screen! I believe there entrance is the vent on the back, as I don't see any other way of them getting in. I've tried using the hoover on the vent, but still a few remain and they are very small in size. It's incredibly annoying trying to watch or read something and then have a bug crawl its way all over the screen and you can't do anything about it. Has anyone had a similar problem? Any tips or help on how to get them and keep them out would be greatly appreciated! Thanks, Matt.
