Also, can you use APCC's log zipper to zip your logs and place them in the files section, or post a link to a dropbox or other folder?

Subject: [ap-gto] APCC app crash when parking mount (Mach1) - event viewer details #APCC

Yesterday evening I experienced a mount crash; when SGP command issued to park the mount at the end of the
session, apparently APCC crashed.
SGP log and Windows event viewer follow below.
Please let me now if more details are needed.
