That is good to know.  I didn't think that anything with a grey check mark & after the date I was trying to reconcile would change the beginning balance, but that is the only way I got it to balance the 1st time it happened.  
I have been trying to balance April 2015 for 8 days....I have reconciled March & Feb & can't find the error....

Is there a way to make it so when I download transactions from the bank each day, that QB won't put any kind of check mark in automatically (on the matched transactions)?
