I can verify that the SHN utility will run (with some issues) on Vista. I have used it to connect succesfully to an EZSrve.
It finds and connects to the device without issue. If I hit the disconnect it crashes (Vista says SHN Utility Suite stopped working…)
List timers works correctly
List macros pulls the macros into the control window but not the macro window
The control window monitors data correctly.
The manage links window pulls links correctly.
I haven’t tested extensively, as for some reason my Vista laptop intermittently loses TCP/IP connectivity to the EZSrve, so for the most part I’m doing RDP to a Windows Server 2K3 machine for communicating with the EZServe.
