WP #5037 Dataviewer has been updated to version 2.9.1.2 for Ubuntu workstations in the control room. This is to fix bugzilla 775, to prevent incorrect channel names from being entered by the user. An incorrect string comparison of entered names to the channel list read from the NDS allowed certain bad channel names to be entered manually, and since data wasn't available for the incorrect channel, dataviewer would substitute different channel data, leading to confusion.
