Steve (et al),

VERY INTERESTING. But I know what your problem is. Tango is programmed to
blow up this week!!! How do I know? Well, the latest stencil files we
emailed to our stencil house are not readable. Same person doing the
generation, zipping, and sending! What else could it be? Thank you for
bringing the answer to light. We use Tango also.

Actually, I do not know what to think about this situation (mine) because we
finally got a pretty automated 'system' worked out and we did not do
anything different with this one. And to make matters more interesting, our
board design guy is off for a few days!

Wouldn't it be interesting if it turned out this was close to the reason???
Yea, right.

Just my 2cents!
