The revised program addresses a rare glitch in the iVotronic machines, in which the serial number from a unit can appear garbled while votes are being downloaded from a small disc into another machine to be read. A low battery in the first is the culprit, and the updated program certified last week by the state Division of Elections should prevent it from affecting the serial number in the future.
Officials have emphasized the glitch does not affect vote tallies, but they recognize any perceived flaw can make voters nervous.

The problem was in the computer software used at election headquarters to tabulate the votes from each precinct. The software has an "add to/replace" function that could allow votes from a particular machine to be added to the tally multiple times

ES&S has revised the computer software to address the concern. Under the newer version, when workers press "add to," a warning will appear if the votes from that machine have already been added.
