Aye, you can really see it happen when saving over an existing file. On XP, anyway, it will go through it's saving process, then write the image file, then Bryce will just sit there for a minute or more depending on the file size. Based off of what Flak said I think that (since Bryce isn't XP-compliant, really) that it's just having a rough time dealing with the temp files... (deleting them, or whatever.) So if you're not sure that your machine can really handle a scene, when saving it it's best to save it under a NEW filename, then just delete your old one later or whatever. Cuts down on the chances of it crashing during a save...
