Hi Dave,Have you gotten this data file to work with version 1.2b2 before or do you suspect this is a Mac OS X issue?
The GRIB support is rather new and there may be some bugs in the beta 2 version that you are running. We plan to have a new release of the IDV within the next few weeks.
In the mean time, could you make the GRIB file in question available to us (e.g. via ftp) so we can make sure we can support it?
Thanks, Doug Unidata Support wrote:

We just upgraded the RAM on these machines to 1GB (third party RAM). OK, what info have I failed to include here?
