I am currently running a MacBook Pro 15inch i5 processor, and have recently discovered the unfound wonders of screen sharing with another mac (or even to your own external IP address which is allowed by the Finder). I have googled up the "screen sharing to infinity" as it is described wonder where a screen appears inside another and then another and another and gradually it becomes smaller and smaller (as if you have a tunnel of a million screens going towards the centre). I came across this for the first time when i connected my Macbook Pro to its own external IP address (and then relatively quickly quit Screen Sharing). I also seem to have this when i connect my Mac to another mac, and then that Mac connects back to mine (or vice versa) and then on the other mac screen, whenever a fully opened window (such as Safari, Firefox, Skype, Finder etc) is minimised the "screen sharing to infinity" begins on the Other Mac in the screen sharing window (but not actually physically on my own mac). I was just wondering why this happens since i couldn't find any threads pointing to why, as well as how to prevent the problem, if there is a prevention method. Thanks for any help.
