Grace, Thanks for the good news. Note that this situation should be rather unusual so this issue should hopefully not be a problem for most of your users/colleagues viewing the NCEP dataset with the IDV. Fixing this problem with a more permanent solution is high on our priority list, so hopefully we will have a solution soon.
