You aren't asking too much of C4. 1.) If you can reproduce this on cue, send it to support@eovia.com with a good explanation of how to reproduce it. 2.) The code must have memory issues in lots of things. It has video problems for me on both ATI and Nvidia cards, it gets weirded out when I use the metaball modeler, it suffers when I have lots of things turned on during assembly work and am doing lots of preview renders. The code is buggy at the moment but Eovia will fix it (I'm sure about it!). Make sure you send Eovia an email. -Kix
