This doesn't appear to be reproducible on non-Windows machines, and
I'd suspect that Brian checks quite carefully for this kind of thing
on Windows as well. You wouldn't happen to have something floating
around in your workspace that could get in the way? Otherwise try
turning on debug(reshape) and when it is defined also
debug(reshapeWide). Then tell us what is in a and data[, idvar] when
the problem appears.
