Thanks for clarifying this up. I didn't realize 1080 was 1920x1080. For some reason, thought something like less then 1280x1024. I hope we can trigger a switch within the box to show 1024x768 on live playback. I'm assuming we can at this point. I don't plan on upgrading for still another few years. VIM still seems to run find on my 2x750P3 box here, as well as my P3 1Ghz laptop. :-/ I'm sure I'm not the other one who's only need is VIM. But, I'm guessing you had to buy the 2Ghz for Emacs. ;-) -- Roger http://www.eskimo.com/~roger/index.html
