R help - Sep 2011 - Histogram messed up

Hey all,

I encountered a problem drawing a histogram.
You can view the picture here:

What happens:
the bars are drawn with different starting points, thus no straight zero-line is
there.
And bars are overlapping. (or sometimes apart from each other.)


How it happens:
hist(volcano, breaks=10) # and any other data
This also happens with barplot(rnorm(10,10,1), space=0).
resizing the graphics window shows the double line in differing places.


What I thought may cause it:
Just installed "xlsReadWrite", but I don't think that should be a
problem, even though it's kind of irregular, with the xls.getshlib().
I restarted R when I noticed this, but even without lybrarying the package, it
still happens.
I only recently upgraded to R 2.13.1, so I'm not sure it didn't happen
before the package.
It did not happen with older R versions, that I do know. But that isn't
necessarily causal.


What I want to know:
Any idea what may be causing this? Or better yet, what may be solving this?
Am I the only one with the problem? Could it be a bug? Is it my computer?

Any help would be highly appreciated!


What you may need to know:
Im using R on a Windows XP machine.
