Steve / Kamesh,
We have received our zephyr upgrade for our SLA500 and have been told by
3DSystems field service to delay the installation until "bug fixes" are
implemented into the software. To date, the details as to what the exact
problems are have not been explained to us but we have the upgrade sitting
on our receiving dock ... waiting.

Have you heard any details that might correlate your crashes to software
bugs? Thanks.
