Mighty Pete and I went round and round with this issue last year. How ya doin' Pete? The easiest thing to do is shut Vue down and open it back up before you render. It'll give back the resources so your render will go smoothly. There's no way to 'fix' it. Do follow the above tips...background apps, mem management etc. I'm convinced that Windows and Vue do not get along when it comes to virtual memory access. I've gotten in the habit of shutting Vue down and opening it back up between major tasks. It's the only way I get anything accomplished in it. You'll get used to it. Maybe it'll be better in Vue 5 whenever that is. Yours, Monsoon
