Don't know if this is related, but today SU crashed several times when I tried to export a animation. I tried other smaller models, etc. to no avail. I finally uninstalled SU 7.1.2 (my own numbers) reinstalled 7.1.1, and again 7.1.2, both times with no success. I noticed that in some cases, the failed export left a empty *.avi in a folder at a higher level then the data folder. So I moved the model to the Win desktop, opened, and successfully exported the avi. Maybe SU has problems (in some instances) with long path names.
My data folder name- C:\Documents and Settings\Atelier\Data\Job\Gfh Gary Hokua\Models renders\Furuta Hokua Desk
The folder I found the empty avi on crash- C:\Documents and Settings\Atelier\My Documents
The desktop subdirectory (folder)- C:\Documents and Settings\Atelier\Desktop
**Adenda 1: I just finished the export and the file ended up in C:\Documents and Settings\Atelier\My Documents
???? I must be doing something s*$&^d**
Adenda 2: Of course, the default folder is the above, I just had been assuming that it was the data folder. Everything works now????
