[idvusers] Aggregate grids by time bug

Does anybody know if the issue with intermittent nature of "Aggregate grids
by time" has been solved? I got it to work once in about 20 attempts. I
know it's been an issue in the past.
(e.g.,
http://www.unidata.ucar.edu/support/help/MailArchives/idv/msg06915.html).
Is there some other method available?
