This is the third or fourth time I have run into this, but never alerted programming.
 
If someone enters an employee in division "A" and saves the record, and then it is discovered that the wrong division was used, changing the division to division B with different payroll expense accounts, does not automatically reset the expense accounts in the defaults for that employee. That seems counter intuitive. You must then go into the employee setup and change the expense accounts manually.

i had this problem and totally forget to edit the individual accounts in PR-A.  Caught them just now (six months later I might add...) but can not "SAVE" the changes.  every time i try to click the Main Menu button it kicks me out.
 
HELP... i now have 2 employees to fix.
