Yesterday a client told me of a serious issue he was seeing. Saving a study collection or loading one causes the ID numbers to be re-numbered sequentially. This causes problems as the studies that refer to the old ID numbers are not getting updated, so the connections break.
Sierra Chart has acknowledged that there was a bug in version 1996.
It is recommended that you skip version 1996 and go to version 1997 or higher.
