Thanks Don! I need to keep you busy before you leave!!!
Couple related questions:
1. Is there a way (or future plans for) to use a different vertical
coordinate than height? Typically in a cross section one uses pressure
as the y-axis. Also, when using isosurfaces with one parameter colored
by another, it would be nice to be able to have, say, the jet core
colored by pressure in hPa instead of geopotential height in gpm.
2. Can parameters be scaled (aka like the SCALE parameter in GEMPAK) by
powers of ten? Say I wish to display height values in decameters
instead of meters?
Cheers, Kevin

Kevin-
Oh sure, just when we are about to do a release, you have to find a
bug. ;-)
I've implemented a fix and it will be in the next nightly build (and
the 2.9 release). Thanks for catching this.
To the list, we are planning a 2.9 full release next week. Please
check out the test release at:
http://www.unidata.ucar.edu/downloads/idv/test
(or the nightly build) and let us know ASAP of any issues you find.

I've run into this problem where if I try to draw cross-sections on a
derived field (e.g., potential temperature) and try to load more than
one forecast time, the display will not appear and I get the
following errors:

The problem also occurs with another derived field (Relative
humidity), and with different NWP models, so I suspect this may be a
general problem with "derived" quantitites. I've run this on both
OSX and Linux 64-bit systems . . .
Thanks,
Kevin
