Hi, Yes we use Cunninghams Epos Impact in our school and we often have this issue and many other problems. The call centre (which it now seems to be) very often blames 'the network'. Since the company was taken over by Jonas, a Canadian software house, the support seems to have gone downhill. We are looking to switch to NRS (Nationwide Retail Systems) which is a British owned company. Their support seems to have good testimonials from others I speak to. As you imply, the problem began after the corruption so it would make sense to investigate how it could be related. However, with Jonas/Cunninghams, time is money and unfortunately they do seem to use the 'network' chestnut excuse extremely regularly!
