R help - Apr 2003 - Windows: Graphics appear only partially

Dear all,

we have installed R in one of our computer labs. Running demo(grpahics)
works, kindof, in that it produces all the usual plots without crashing, but
the plots are incomplete: no color wheel, no pie chart, no boxplots, just
some labelling, titles, and in rare cases, axes. We have tried this with
both 1.7 and 1.6.2, with the same results. The computers are running Windows
2000, with somewhat elderly video cards (NVidia Vanta with 8 mb of video
RAM), the monitor is set to 1024x768 and "true colors" (32 bit).

Has anyone suggestions why this might be? What might be done?

Thanks!

alex

I've no real idea: I used to run R happily on a W2k laptop with only 2.5Mb
of video memory (1024x768, 24bit).  Looks like a graphics driver problem to
me: can you try 24bit or failing that 16bit?
