Using R-help to report a problem in Rstudio?

When reporting graphics problems, you need to report the graphics 
device you use, as well as the 'at a minimum' information required by 
the posting guide.  This looks like a problem in Rstudio's own 
device/UI, but I am guessing from the file name.

If you use an alternative front-end such as Rstudio or Tinn-R (or even 
RKWard) please do mention it in your posting.
