i don't know what happens exactly, but my internet connection keeps getting interrupted while i'm playing spiral knights (it's not that i'm dcing from SK, i'm dcing from eeeeeeeeeeeeverything), and i have to restart my laptop to get it going again. sometimes i am able to log back on in time to still be in whatever depth i was in, but more often than not lately i wind up back in haven. which, you know, that's just great after beating all of an arena level and having a thingy full of heat.
this only happens while i'm playing spiral knights (using the downloaded browser thing, i haven't tested it using the web thingy), or else i'd just chock it up to my laptop being (relatively) old.
edit: ok evidently using the web thingy at http://www.spiralknights.com/play.xhtml just causes my computer to freak out about memory allocation and force-shut-down itself via blue screen of AAAAAAGGGHHHHH. *sigh*
