As a follow up to this: I have found that the issue was not the change of machine or OS, but the addition of displaying several charts/symbols at one time on the new machine while running the process mentioned.
In order to work around the problem I now set a global layout called "No Charts" which closes all charts. I then run the procedure. I have not experienced any problems since.
