i recently went on a scan run and now whenever i load my planets my computer warns me that it might freeze i don't have dial up and was wondering if anyone else who has encountered said problem has a solution for it.

It's based on the number of planets you have and the browser you are using, and how fast your computer's processor can process the javascript that sorts the planets.
Internet Explorer is the first to give the message (low hundreds)
Firefox hits it next (mid hundreds) and as you get closer to a thousand eventually even Chrome will give the message (Lycan says in his last days he had started seeing it in Chrome)

Best workaround: use chrome to play the game, and don't scan so many that you hit Chrome's threshhold

Dan really needs to change how the planet page works so it doesn't load 500-1000 planets all at once and try sorting all of them every time you try to purge or flag one.
