Having some difficulty in Vue4, I'm able to render out at as large as 1600x1024, but when I go to render out a larger image, i.e. to file, Vue seems to dissappear / lock up. I am reluctant to close the app, but it doesn't show it progressing.. Is it still rendering? I'm trying a 4000x3000 render at Ultra... or will this take me a week? Machine = 1.6Ghz, 512Mbs Ram. Thanks!
