SAN ANTONIO -- Early voting in Bexar County hit a snag Monday morning when at least three polling sites experienced computer problems.

The three polling sites were back online by Monday afternoon after a problem with phone lines, officials said. When voters arrived at 8 a.m. to cast their ballots at Wetmore Elementary School, Blattman Elementary School and Johnson Library, computers were having trouble dialing up phone lines that access voter registration information. But according to election officials, a backup program was used, and a half-hour later, the problem was fixed.

Officials said voting machines were not affected by the snafu and that elsewhere around town, things were running smoothly.
