We have discovered an issue in the Navigator Meteor server EXE (v8.6.4.5), and had our engineering team correct it. The new Navigator Meteor server EXE (v8.6.4.6) fixes the issue where the WebAPI can not keep a stable connection to the print engine. In the Colordyne UI the printer status toggles between connected and disconneted every few seconds. 

You simply exit out of the server and replace the existing XiFlowServer.exe (v8.6.4.5) with the one in the link below (v8.6.4.6). This is only to used with Navigator Meteor Server version (R7)

Typical XiFlowServer.exe location: C:\Navigator\Navigator
