Perhaps you could fix the 1/3 line problem at the same time (not that it bothers me really, but it makes sense to kill two birds with one stone) A artifact which I find more anoying is other flicker areas on the screen. my screen looks like this (out of perspective) **+++++ <1 (1/3 line flicker) **+++++ <1 ++++++++++++++++++++++++--------------------------------------xxx++ <2 --------------------------------------------------------------xxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 ......middle of screen removed.... -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 -WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWxxx++ <2 --------------------------------------------------------------xxx++ <2 ------------------------------------------------------------** <3 * = flickers a lot + = flickers some - = normal video, unused x = normal video, can't be used (WHY NOT!?!?) W = normal video, occupied by workbench (massively overscanned) The 2 stuff crawls upward but isn't too bad. The 1 and 3 stuff is very annoying. Also ("you mean there's more?"), I have what I beleive is an actually defective 2320. When I first turn on the machine after it's been sitting for a while (> about 4-5 minutes) the whole video signal is "spattered" with red and cyan (not blue, cyan) dots in a repeating, but difficult to describe, pattern. If it turn the machine off and then back on (after >safety time but <4-5 minutes) then everything is fine. It sounds to me like something a capacitor isn't getting charged in time on the first try or something (...based on my limited hardware knowledge, I'm a "software type" :-). Any ideas? I haven't taken it to a dealer yet since the closest one is quite a ways away.

Hey! Hacker! Leave those lists alone! All in all it's just a pure-LISP function call. All in all it's just a pure-LISP function call.
