We have a similar problem. Rick's suggestion of 'just issue credit' is wonderful - and about as useful as a marsmallow hammer. With solutions like that, who needs problems?
In our case, we have account payments that are double-posted by RMS - not by my cashiers. A $300 payment shows up as a $600 credit on account. The paper receipt and the journaled receipt are both for $300. I have my reseller coming to look into it. If you work with a reseller, it's been my experience that when the reseller sends an issue to MS that MS tends to give it a much higher level of attention than they do if you bring it to MS' attention as an end user.
