Vista is very slow after a TGML graphic is opened

Issue

Vista is very slow after a TGML graphic is opened, it takes like 30 seconds to open a small folder.

Product Line

TAC Vista

Environment

Vista 5.1.6

Cause

A Loytec NIC USB used as the Lon interface is not online because the engineers computer is not connected to the Lon network. But the Xentas and Lon network under the Lon interface are online in Vista for some reason. So Vista tries to read the values from the Xentas and this makes Vista hang for periods of time.

Resolution

  1. Create a new Lon Network interface
  2. Drag and drop the Lon network to the newly created interface
  3. Drag and drop the Lon network back to the original interface
  4. Now the Xentas show up as offline
