Hi karen-bomac
From experience, I can tell you MYOB's script addresses some of the long decimal issues, but not all. Where the long decimal is a single amount, their script will fix it. However when it is caused by a combination of numbers, their script won't as it doesn't detect these. I had a user contact me after MYOB ran the script 6 times to no avail. I referred this to a MYOB specialist who identified and fixed the problem. However until MYOB fix the actual software causing the problem, the issue may well re-occur. So best to put pressure on MYOB to fix. If you want contact details for specialist if MYOB cannot or will not fix, send me an email.
