(Please post messages in "plain" mode, they are much easier to answer)

Thank you for reporting this problem. I will try to reproduce it.

In addition, I will say a few words about your version of midas:

> GIT revision: midas-2019-09-i-1-gd93944ce-dirty on branch develop

I recommend that for production systems one used the tagged release versions of midas. 
(i.e. see https://midas.triumf.ca/elog/Midas/1750).

(Your midas is "1 commit after the latest tag" - the "-1" in the git revision).

I apply bug fixes to both the release branch and the develop branch, but for you to get 
these fixes, on the develop branch you will also "get" all the unrelated changes that may 
come with new bugs. On the release branch, you will only get the bug fixes.

In your midas version it says "-dirty" which means that you have local modifications to the 
midas sources. With luck those changes are not related to the bug that you see. (but I 
cannot tell). You can do "git status" and "git diff" to see what the local changes are.

It is much better if bugs are reported against "clean" builds of MIDAS (no "-dirty").


K.O.
