[GEMPAK #YOQ-706010]: Problem since upgrading to 5.11.1

Hi Allan,

I apologize for the slowness of response to your inquiry.  Our GEMPAK guru, 
Steve
Chiswell, left Unidata back in January, and we have been struggling to provide
the support that our user community needs while searching for a replacement.

We have had several inquiries that point to their being problems with the 5.11.1
release.  We were under the impression, however, that the problems were isolated
to Unidata-added routines.  Your problem seems to indicate that the problem with
5.11.1 may be located in core GEMPAK code.  Finding and fixing the problem will
unfortunately take us some time.  Until we can fix the code, it might be best if
you reverted to use of GEMPAK 5.10.2.

I did look at your scripts last week and did not see anything that looked 
obviously
wrong.  A couple of us will take a new look to see if we can figure out a 
solution
or workaround that would keep you from having to revert to 5.10.2.

Again, we apologize for the slow response.

Cheers,

Tom
