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 ------------------------------------------------------------------ | Angelo J.

erase.screen bug?

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.
