This was originally from the sourceforge list last year.  I just tried  
again, and the behavior is a bit different from what I remember, but  
could still use some attention, although it may still be lower priority  
than other things to be done before release.

First, if I enter a 0% interest, I still get the same error that the  
numbers don't match.  However, if I leave the interest rate missing,  
then KMM does calculate a 0% interest.  Further on this, the calculate  
button only becomes enabled if I fill in a payment amount.  Both the  
interest and number of periods default to 0, but I can blank out the  
interest but not the number of payments.  If I let KMM calculate the 0  
interest, and then change something else to the same value (to  
re-enable the calculate button) hitting calculate gives the same error  
again.

With a 0% interest rate, it still requires me to set a category for  
interest payments.  I suppose it's reasonable, since the interest rate  
might change in the future, but it seems unnecessary.

My original suggestion was just to change the "calculate" error for a  
0% interest rate, which still makes sense, although it's odd that KMM  
will actually calculate a 0% interest rate.
