Yes, same problem when placing orders...but mainly for only one of three providers. We are on v5.0.24 but per the update website it says support is still working on the issue as they are having a hard time replicating at the company. we also are using Windows Server 2003. This is the only big bug that we are having w/ V5, otherwise loving it! (we are also getting error 91 (?) when we close the application but doesn't seem to harm anything.
