a) Do not file a bug report if there is no evidence for a bug (you say 
yourself it works on another machine).
b) Do upgrade  before posting a bug (at least you .0 version of R, and 
in a next step (here not so important) your Windows).
c) Try to start a clean version of R:
I mean without loading some strange objects in your workspace or some 
packages that might break some important R properties.
