Bug in interest calculation

[Bo Najdrovsky]

It's been a long time since I've posted anything to the list, but I 
think I discovered a new bug, which as introduced within the past year, 
so I thought I'd rejoin the list.  It appears that the ipmt() and ppmt() 
functions no longer function properly in scheduled transactions.  I have 
a couple of loans that are set up in my scheduled transactions, and up 
until September of last year, everything was working fine.  Then 
suddenly, beginning with the September payments, the interest and 
principal have been remaining the same for every month since then, 
instead of what should be happening, which of course is that the 
principal value should be growing while the interest value is dropping. 
I suspect that this issue coincided with a GnuCash package upgrade to my 
current version. Sorry if this is already a known issue, I searched the 
list archives to see if anyone has already reported this and didn't find 
anything.

I'm running the standard Fedora 7  build of GnuCash 2.2.1, which comes 
with this particular distribution.  I don't recall what version of 
GnuCash was on my system prior to September, but I'd guess it was 
perhaps the 2.0 series? Anyway, my principal and interest balances are 
now quite a bit off from what they should be, so I thought I'd try to 
report the issue.

thanks,
  Bo
