R help - Jun 2003 - erase.screen bug?

Hi,

I'm using R 1.7.1 on a Windows 2K computer.  For some reason erase.screen
does not seem to be working correctly.  That is it does not erase the
requested screen.  That is the old graphic is still visible and any
subsequent graphics are superimposed over it making them impossible to
read.  What is worse is that they print out this way also.  The same
behaviour happens with a Windows XP computer.  I have not yet examined
this on Unix but will do so tomorrow.  Is this a known problem?  Is
there an easy workaround?

Thanks,
Angelo

Is your background colour set to transparent?  There is no way to erase 
screens in the R/S model: all you can do is overpaint with the background.
And the default on-screen background colour is ... transparent.

This described in the Warning (and elsewhere) on the help page.

With a solid background colour it appears to work.
