I had encountered a similar problem when changing the font in the R Console and
then then open the graphics device by plot(), the console window whites out. 
this might be related to bug report 7271.  I mentioned it sometime back and was
told is was not reproducible.

Now I have encountered a similar problem that does not appear to relate to the
graphics device. I started an R session, changed the font to size 8, Apply/OK. 
Then I opened a help page by typing 
> ?plot
the R help page opened in a different (system?) font and the font in the console
also changed to the same bold-face, non-proportional font.  Then when I typed
another help command, the console completely blanked out.

There seems to be some strange interaction going on between new windows opened
by the system and the font setting in the GUI preferences.
