First off, those .tmp files can be renamed to 'anything.br5' When Bryce crashes it dumps your current project into a .tmp file and saves it - be warned! This does not always occure!!!! 2nd. Always TEST your new d/loaded objects using a NEW Bryce workspace. If they work ok you can then put them into your 'CREATE' drop-down and save them for use in your current project. 3rd. Bryce is limited by the capacity of your computer. You need loads and loads of RAM. Some of us here have over 1gig RAM and even that's not always enough. Having said that, simple stuff like good housekeeping will keep Bryce running with no problems even on a basic system. 4th. When Bryce starts acting up, save your project (you should do this often anyway) clear out your .tmp files and re-boot. 5th. Something I've learned but never passed on - Bryce will speed up if you change the NANO-PREVIEWS to WIREFRAME. Finally, if you are an experienced pc user then you probably know most this anyway, and you should not take this as an insult to your intelligence. Hope this helps. Regards The Bryster
