Hi Garyn,
I can only add my name to the list of those affected by this issue. We are on RMS 2.0.2007. Windows 7 Professional on PC's. SQL Server 2012. We were using Heartland to process. We were using (3) Verifone 1000se pin pads for our (3) lanes. All lanes were impacted with the issue. This issue occured often enough that our staff stopped trying to process debits as debits, and ran all as cc's (undesirable). I spoke with Heartland and they dismissed it as a POS side issue and referred me to our reseller.
Last week, we upgraded our system to Cayan as our processor and are now using Verifone MX925. We no longer have the problem.
