Since (s)he used windows() we know the OS.  But I think one possible 
explanation is on the help page, arguments 'xpinch' and 'ypinch': most 
likely this is one of those devices with a mendacious Windows driver.

Of course. we simply do not kwow what (s)her saw, and it is possible 
that this is simply a misunderstanding of 'plot region'.
