Sharen - XP is okay with Vue 4. The wonderful thing about aXP is that, its an OS that would never crash with any application crash. Just have to end your task and start the program again. Like Laurie said "I did notice tho that your pictures will still not save to the pictures folder, even tho previous ones are listed there in the dialog box, but when you physically go to the folder they are not there"... This is the problem I'm having and its RANDOM ...but be sure you do not export the image as Vue default which is "all picture files"...choose a "bmp,tiff" or something. Moreover rendering in Ultra sometime complete but mostly don't (12% to 65%)for me. Rendering to disk..I'm not sure..just ain't have the patient to wait with my kind of scene file size. Broadcast and final is the same as with Ultra intermittent problem but less prone. The risk of incomplete rendering goes up when my rendering pixels size is goes over 1095 X 822 which is the Vue default. This again could be what is use in the scene..like the one Bloodsong had with his waves pounding on shore or something like that that causes it. Vue 3.1 works fine with XP on my system as I have mentioned here earlier in one of the beta 4.03 thread here. All other program that I have been using all runs on XP. Please note that the above may be peculiar to my system and software config...like Varian use to say, mileage varies. Just for info...XP professional version (not home user version), Dual CPU (1G), 1 Gig Expandsion RAM, Mixed Format HDD (SCSI 'n' 100/ATA) total 7 of them, 3d Lab VX1 32Vmeg(X4) and ASUS CUV4X-D MB.
