Computer glitches plague US voters

Frozen screens and malfunctioning computers plagued some voters who tried to cast electronic ballots in yesterday's "Super Tuesday" contests to win the Democratic nomination for this year's US presidential elections.

Experts predicted such problems will be repeated on a national scale in November's presidential election.

In California's San Diego County, touch-screens failed to boot properly, causing delays of up to two hours and forcing some voters to other polling places - where they cast old-fashioned paper ballots.
