Hi Ronald
I just replaced a broken register with a new one and assigned the same register number as the one it replaced. I installed ezPower(V13) using the install exec I received originally. All seems fine until I try to Z-out this new till. When I do, the ezPower program stops responding on all other registers and the only way to get them back is to reboot all registers(the server appears to be fine). The main difference with this new register is that it is running Windows 7 where all others(including the server) are running XP. I've searched thru this forum for possible causes with no luck. I have double checked firewalls, sharing parameters etc and everything looks fine. I have reset Z-out to the current date. The register works perfectly fine until I hit Z-out then everything just stops. Any ideas?
