Heh, my CRT was new as of 2002 or so. It was a Gateway EV700. Couldn't set it at 72Hz unless you wanted it to burn out in a few months flat. Also I noticed (but I have good eyes for this thing) that it flickered like a neon light at 72Hz. Probably just a cheap POS, but there are lots of cheap POS's in the world. Word to the wise, if it starts acting funky drop the refresh to 60, and see if that fixes it.
Not that it'll fix this AH bug. Have they released a patch yet? (I've not logged in for 24 hours almost)
