Re: Uncover bullet points with BEAMER_env: ignoreheading

[Derek Thomas <derekcthomas@gmail.com>]

It seems that with the options you suggested, the "[<+->]" argument is
passed to the \columns environment instead of the \itemize environment
within the column.  Beamer doesn't accept this argument for the
columns environment.  Is there a way to pass the argument to \itemize?
Thanks,

Derek
