Sky... 256Meg might not be enough ram if as you say the object is very large... looks like this is your problem as I believe the Kern32 DLL (part of windows) deals with memory allocation. Ram is extremely cheap these days - Last week I upgraded from 256 to 768Meg and it only cost me 45UK ($64US). Strangely, I havn't had a single Bryce crash since! And I didn't mean to worry you about corrupted files... but it happens. It might be worth re-installing Bryce anyway as it takes 2 minutes and will not cause ANY bad effects. Then if it still happens get more RAM. Hope you succeed in exporting those objs! Howie.
