SGDataProcs HAVE BEEN FIXED

Zach, et al,

For those of you who are having problems with your SGDataProcs, this bug has
been fixed. We released a seed (6.0.0 d2) almost a month ago that fixes this
problem along with many others.

You may ask yourself "How do I get this seed?" It's actually quite easy and
can be done in three easy steps.

First, you need to be a member of the ADC (at least an online member) which
all of you should already be.

Second, you need to send a mail to email@hidden requesting that you be
put on the seed list.

Third, you will get email from us with a username and password, and also
access to the private QT Java Seed List. You will also get access to our
seeding server where you can download the latest seed.

Please remember, that these seeds are development versions, and may have
issues, so your feedback is greatly appreciated.

I hope this helps clarify things.

Thanks,

Michael Hopkins
