Hm. I'm running 4.11, on a machine with XP home and I've not encountered that (I think it worked on my other machine, windows 2000 on a much slower processor before this new one came ... Yay) I was having Open GL problems, due to a flawed MS Updated driver (went to vender web site and got a partially new one (had to tell windows to replace a few newer files) and now I am quite a bit happier (was frustrated to buy a machine mostly for vue, only to have to fall back to the non-GL interface) I'll tell you one thing, XP ain't quite what you might think by following the press. It's only moderately more stable than 98 and performs considerably worse than 2k (I'm guessing all of the silly bloat crap that I have yet to find out how to get rid of.) I was hoping to splurge on a mac, but alas, just couldn't afford anything that sounded good to me :( I really want to play with OS-X! eric
