Balance Sheet Totals Not Consistent

[Mike C.]

I have a problem with the balance sheet totals that I can't isolate.  
The Total Assets does not equal the Total Liabilities and Equity.  I 
have a large number of investment asset, income, and expense accounts so 
it is difficult to find where the problem is.  The difference between 
the Net Income on the Income Statement and the Retained Earnings on the 
Balance Sheet is about $1000 but the difference between Total Assets and 
Total Liabilities and Equity is about $20,000 on the Balance Sheet.  I 
have tried using both the default accounts and selected all accounts 
with the same answer.
It seems that the program should make these lines equal on the balance 
sheet independent of whether the inputs are correct or not so I don't 
understand how the problem happens.
I am using version 2.2.9 on Windows XP.
Any suggestions on how to resolve this issue would be appreciated.
Thanks,
Mike
